Abstract
The invention discloses an indoor alternating current metal armor switch device which comprises a casing (2) and a number of partition rooms, wherein the partition rooms are partitioned by partition plates (12) and are arranged in the casing (2). The partition rooms comprise a handcart room (A), a bus room (B), a cable room (C) and a relay instrument room (D). A valve (13) is arranged at the wiring positions of the handcart room (A), the bus room (B) and the cable room (C). Pressure releasing devices (1) are arranged above the handcart room (A), the bus room (B) and the cable room (C). The switch device provided by the invention has the advantages that the pressure releasing devices are respectively arranged above the handcart room, the bus room and the cable room; when the internal pressure rises due to a failure, the pressure releasing devices automatically open a metal door to release pressure and discharge gas, so that the safety of an operator is ensured; and a partition door between the handcart room, the bus room and the cable room is changed into the valve, which avoids accidents caused due to the fact that the operator forgets to close the partition door.
Description
Technical field

Background technology
In the defeated change systems of electric power such as rated voltage 12KV, 24KV, often use a kind of indoor AC metal armored switchgear, the inside of this equipment generally seals, when breaking down, because the outlet of electric arc makes air pressure increase, the event of may blasting, bring danger to operating personnel; And be provided with partition door between handcart chamber and bus-bar room, cable vault in this equipment, but partition door is all manual, operating personnel may forget and close partition door, so also easily can cause some unnecessary accidents.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, the indoor AC metal armored switchgear that a kind of security performance is good, easy to operate is provided.
Purpose of the present invention is achieved through the following technical solutions: the indoor AC metal armored switchgear, comprise shell and a plurality of compartments that separate by dividing plate in the enclosure are set, described compartment comprises the 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 slides and work for circuit breaker cart, handcart chamber and bus-bar room, wiring place of cable vault is provided with valve, be provided with main bus bar in described bus-bar room, the little bus of branch and contact box, the little bus of described main bus bar and branch is fixed by the bus sheath box, be provided with current transformer and earthed switch in described cable vault, described relay is provided with the relaying protection element in control room, instrument, charged supervision indicating device, described handcart chamber, bus-bar room, the top of cable vault is provided with pressure relief device.
Described shell and dividing plate adopt the deposited plumbous zinc steel plate of 2mm.
In described cable vault, lightning arrester is installed.
Be provided with grounding copper bar in described cable vault.
The inside of described handcart chamber and cable vault is provided with heater.
The invention has the beneficial effects as follows:
(1) in the handcart chamber, cable vault and bus-bar room upper end be provided with a pressure relief device separately, breaking down while causing air pressure inside to increase, pressure relief device can be opened metallic door automatically, discharges air pressure and excretion gas, has guaranteed operating personnel's safety;
(2) make the partition door between handcart chamber and bus-bar room, cable vault into valve, when handcart moves to service position from test position, valve can be opened automatically, and handcart is while getting back to test position, valve is closed automatically, so both facilitated operating personnel, and can avoid forgetting to close because of operating personnel the accident that partition door occurs.
The accompanying drawing explanation
Fig. 1 is inner electrical equipment structural representation of the present invention;
Fig. 2 is front view of the present invention;

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As Fig. 1, shown in Fig. 2, the indoor AC metal armored switchgear, comprise shell 2 and be arranged on a plurality of compartments that separate by dividing plate 12 in 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 described handcart chamber A, handcart chamber A also is provided with the guide rail that slides and work for circuit breaker cart 6, handcart chamber A and bus-bar room B, wiring place of the C of cable vault is provided with valve 13, when circuit breaker cart 6 moves to service position from test position, valve 13 can be opened automatically, and circuit breaker cart 6 is while getting back to test position, 13, valve is closed automatically, operating personnel had so both been facilitated, and can avoid the accident of forgetting to close the door and occurring because of operating personnel.
Be provided with main bus bar 5, the little bus 3 of branch and contact box 7 in described bus-bar room B, the little bus 3 of described main bus bar 5 and branch is fixing by bus sheath 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 while causing air pressure inside to increase, and pressure relief device 1 can be opened metallic door automatically, discharges air pressure and excretion gas, has guaranteed operating personnel's safety.
Described shell 2 and dividing plate 12 adopt the deposited plumbous zinc steel plate of 2mm, and the switch cubicle therefore assembled can be protected the uniformity on size.Switch cubicle has very strong anticorrosive and antioxidation, and the mechanical strength higher than equal steel plate arranged.
