V. Instruction of the structure
The cabinet is composed of the fixed cabinet body and the drawable part (the drawers). The cabinet shell and the interval boards are all bolt with aluminum zinc alloy boards. The protection degree of the cabinet shell can reach up IP4X, and IP2X of each interval room.
The cabinet has the functions of overhead inlet and outlet, cable inlet and outlet and left-right contact. Arrange the scheme cabinets according to usage to compose a power distribution device which can fulfill the designed function.
The installation and the commission of the switchgear can be done in the front. The cabinet can stand by the wall to save the floor space and lower the investment.
1. The cabinet body
The body and the interval boards of the cabinet are bolt by aluminum zinc alloy board after the process of CNC machine tool and multi bending technology, so that the cabinets assembled can guarantee the unity of the structure and the dimension. The aluminum zinc alloy board has the functions of corrosion resistance and oxidation resistance, and has the higher mechanical robustness than the ordinary steel board. The cabinet is divided to drawer room, bus bar room, cable room and relay instrument room by the interval boards with each unit grounding separately. The doors of the cabinet are all handled with the technology process of electrostatic gunning to make the surfaces have the advantages of anti-impaction, corrosion resistance, and beauty and so on.
2. The drawer
The drawers can be classed to circuit breaker drawer, voltage transformer drawer, metering drawer, separation drawer and station used variety drawer according to different usage. The drawers with the same usage can exchange each other. The drawers have test/separating and working positions inside the cabinet, each position with an interlock unit to ensure the drawers can't move freely in the above two positions.
3. Circuit breaker drawer room
A special channel has been installed in the isolation room to provide the drawer to move. When the circuit breaker is moving between the test position and the working position, the separating valve automatically opens or closes to ensure that the operating staff can't get in touch with the charged body. The drawers can be operated in the condition that the cabinet door is closed. The position where the drawer is inside the cabinet can be seen through the monitoring window, and any of the labels on the drawer can also be seen. All these guarantee the safety of the operating and the maintenance staff.
4. Bus bar room
The main bus bar is lead from one cabinet to another cabinet and it is firmed by branch little bus bar and electrostatic contact box. It is fixed by bus bar bushing when it goes through the side wall of the neighbor cabinet.
5. Cable room
Adequate cable room not only can connect many cables, but also can install current transformer, grounding switch and lightning arrester and so no.
6. Instrument room
The internal plate and the panel of the relay room can install control and protection elements, the meter, the displaying instrument and the monitoring indicator and so on secondary elements.
7. Interlock unit
The cabinet has a reliable interlock unit in accordance with the "five-prevention" requirement, which actually guarantee the safety of the operating staff and the device:
a. An attention button and an alternation switch KK are installed on the room door to avoid the error switch on/off of the circuit breaker;
b. The circuit breaker can not move after switching on in working position to avoid the error pull or close of the separating contact;
c. The grounding switch can switch on only the drawer of the circuit breaker exits the cabinet and the drawer can not enter the cabinet at the same time (the grounding switch can match a voltage monitoring unit). The grounding switch can not switch on when the drawer is in the cabinet, thus fulfill the preventions of closing the grounding switch with power and closing the circuit breaker before the grounding switch is open;
d. The bottom door and the back door can not open after the circuit breaker entering the cabinet to avoid the error entry with power interval;
e. The drawer of the circuit breaker can switch off manually only without switching on when it actually is in test or working position and has no control voltage;
f. The secondary plug is locked and can not be pulled out when the drawer is in working position.
8. Grounding position
In the cable room, TMY40*4 grounding bus bar has been set independently. This bus bar can go through every neighbor cabinet and can get a good connection with the cabinet body to ensure the safety of the operating staff and the cabinet body.
9. Pressure releasing unit
Pressure releasing units have been set at the upside of the drawer room, bus bar room and the cable room. When the circuit breaker or the bus bar arises inner electric arc, with the appearance of the electric arc, the air pressure in the cabinet grows and the pressure releasing unit will automatically open to release the pressure and air when the pressure reaches up to a certain value to ensure the safety of the operation staff and the cabinet body.

VII. The installation of the switchgear (see the attached diagrams)
1. Basis style
The construction of the basis of the switchgear shall conform to the relative specification of "technology specifications of electric power construction and inspection".
The installation basis of the switchgear needs to water the concrete twice. The first time to water the concrete is for the installation components of the switchgear that is for the angle steel, square steel or the installation basis of the channel steel. The second time is to water the additional layer of the concrete, usually 60mm in thickness. The height of the concrete shall be 1 to 3mm lower than the surface of the component when water the additional layer of the concrete.
See the attached diagrams for the basic structure frame.
The installation quality shall be ensured when install the basic structure frame. The technology standard of the installation of the structure frame is 1m2 with 1mm tolerance.
2. The installation of the switchgear
See the attached diagrams for the installation basis and installation dimension of the switchgear.
When the cabinet body is unistrand, the passage before the cabinet is 2.5m for the best and 3m when biserial.
Transport the switchgear to the certain place according to the need of the project and the indication of the diagram. If arrange a long line of cabinets (more than 10 sets), the arrangement work shall be started from the middle.
Use special transportation vehicles such as cranes or forklifts. Rollers and crowbars are prohibited.
Take out the drawer of the circuit breaker inside the cabinet; put it in another place for good care.
Loosen the switch to move away the cable cover.
Move away the cover from the control slot on the left side of the cabinet. The cover of the control slot on the right front side shall be moved away in the same way.
Disboard the lifting board and the fastener.
Install the cabinets in sequence on the above basis. The installation plainness of the switchgear shall not exceed 2mm both in horizon position and in vertical position.
When finish the switchgear assembly, it can be connected with the basic structure frame by ground crews or welded by electro-welding.
3. The installation of the bus bar
The bus bars in the switchgear are all segmental square bus bars. Only the quantity and the specification of the bus bar are different when different current has been chosen, thus the following installation processes have to be followed:
Clean the bus bar with a soft clean and dry cloth; check if the isolation bushing is damaged; coat the connecting parts with some conducting cream or neutral Vaseline.
Install the bus bar one cabinet after one cabinet; connect the bus bar section with the corresponding branch small bus bar and insert proper pads when bolting; fasten it with screws.
4. Grounding unit of the switchgear
Connect the grounding bus bar of each cabinet on the preinstalled connecting board;
Connect all the grounding lead inside the cabinet;
Connect the basic structure with the grounding terminals;
Connect the grounding line of the grounding knife switch with the main grounding bus bar of the distribution plate.
