The purpose of the utility model realizes through following technical proposals: indoor AC metal iron-clad switchgear; Comprise shell and a plurality of compartments that separate through dividing plate in the enclosure are set; Described compartment comprises handcart chamber, bus-bar room, cable vault and relay control room; The indoor circuit breaker cart that is provided with of described handcart; The handcart chamber also is provided with the guide rail that supplies circuit breaker cart to slide and work, and wiring place of handcart chamber and bus-bar room, cable vault is provided with valve, is provided with main bus bar, the little bus of branch and contact box in the described bus-bar room; The little bus of described main bus bar and branch is fixed through bus cover box; Be provided with current transformer and earthed switch in the described cable vault, be provided with relaying protection element, instrument, charged supervision indicating device in the described relay control room, the top of described handcart chamber, bus-bar room, cable vault is provided with pressure relief device.
Described shell and dividing plate adopt the deposited plumbous zinc steel plate of 2mm.
In the described cable vault lightning arrester is installed.
Be provided with the ground connection copper bar in the described cable vault.
The set inside having heaters of described handcart chamber and cable vault.
The beneficial effect of the utility model is:
(1) in the handcart chamber, cable vault and bus-bar room upper end is provided with a pressure relief device separately; Breaking down when causing air pressure inside to increase; Pressure relief device can be opened metallic door automatically, discharges air pressure and drains gas, has guaranteed operating personnel's safety;
(2) make the partition door between handcart chamber and bus-bar room, the cable vault into valve; At handcart when test position moves to the service position; Valve can be opened automatically, and handcart is when getting back to test position, and valve is then closed automatically; So both made things convenient for operating personnel, and can avoid forgetting to close the accident that partition door takes place because of operating personnel.
Description of drawings
Fig. 1 is the inside electrical equipment structural representation of the utility model;
Fig. 2 is the front view of the utility model;
Among the figure, A-handcart chamber, B-bus-bar room, C-cable vault, D-relay control room; The 1-pressure relief device, 2-shell, the little bus of 3-branch, 4-bus cover box, 5-main bus bar; The 6-circuit breaker cart, 7-contact box, 8-current transformer, 9-earthed switch; The 10-heater, 11-lightning arrester, 12-dividing plate, 13-valve.
Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the structure of the utility model is not limited only to following examples:
[embodiment]
Like Fig. 1, shown in Figure 2, indoor AC metal iron-clad switchgear comprises shell 2 and is arranged on a plurality of compartments that separate through dividing plate 12 in the shell 2; Described compartment comprises handcart chamber A, bus-bar room B, the C of cable vault and the D of relay control room; Be provided with circuit breaker cart 6 in the described handcart chamber A, handcart chamber A also is provided with the guide rail that supplies circuit breaker cart 6 to slide and work, and wiring place of handcart chamber A and bus-bar room B, the C of cable vault is provided with valve 13; At circuit breaker cart 6 when test position moves to the service position; Valve 13 can be opened automatically, and circuit breaker cart 6 is when getting back to test position, and 13 at valve is closed automatically; So both make things convenient for operating personnel, and can avoid the accident forgetting to close the door and take place because of operating personnel.
Be provided with main bus bar 5, the little bus 3 of branch and contact box 7 in the described bus-bar room B, the little bus 3 of described main bus bar 5 and branch is fixing through bus cover box 4.
Be provided with current transformer 8 and earthed switch 9 in the described C of cable vault, be provided with relaying protection element, instrument, charged supervision indicating device in the described relay D of control room.
The top of described handcart chamber A, bus-bar room B, the C of cable vault is provided with pressure relief device 1, is breaking down when causing air pressure inside to increase, and pressure relief device 1 can be opened metallic door automatically, discharges air pressure and drains gas, has guaranteed operating personnel's safety.
Described shell 2 adopts the deposited plumbous zinc steel plate of 2mm with dividing plate 12, so the switch cubicle that assembles can be protected the uniformity on the size.Switch cubicle has very strong anticorrosive and antioxidation, and the mechanical strength higher than equal steel plate arranged.
