Therefore, the improved switch cabinet abandons a back seal board which is arranged at the back door of a morally-used switch cabinet in the prior art, leads the bus room of the switch cabinet and the cable room thereof to be arranged in a splitting way, and is respectively, correspondingly and independently provided with the cable room door and the bus room door, thereby preventing the electrified bus in the bus room from being touched since only the cable room door can be opened when overhauling the cable room equipment, and being capable of opening the cabinet door within a shorter time when the cabinet door needs to be opened in emergency.
Description
Technical field
The utility model relates to a kind of switch cubicle, especially a kind of switch cubicle that improves existing ZSS-10 type switch cubicle rear cabinet door.
Background technology
The ZSS-10 type handcart switch cabinet that is applied in electric substations such as 110kV Sihong, the county, three li is made up of fixing cabinet and movable part (abbreviation handcart) two parts.By nearly 8 years use, we find to deposit potential safety hazard in the former design of switch cubicle.
Used ZSS-10 type handcart switch cabinet in the prior art, comprise the cabinet of the uncovered setting in rear portion and the back shrouding that encapsulates with this cabinet rear portion opening end, and be to adopt 12 screw location and installation between back shrouding and the cabinet, promptly the back shrouding is not the rear cabinet door on the practical significance, in use has following problem:
When (1) high-tension apparatus overhauls, need be folded down the back shrouding.At this moment, the bus of bus-bar room still is in normal charging operation state.According to rules regulations, in servicely forbid to open the cabinet door.Pull down the back shrouding not only against rules, and staff's personal safety is made threat.
(2) in the relevant rules of cable electrical verification problem the operation of high-tension switch cabinet earthed switch is stipulated: ground connection disconnecting link again closes behind the true no-voltage of identification circuit, because the closure of ZSS-10 type high-tension switch cabinet, must to open behind the switch cubicle the electrical verification operation of circuit and just can carry out behind the shrouding.When therefore equipment changeed inspection operation by operation, the operations staff can't directly use electroscope that the outlet cable end is carried out electrical verification.Therefore, the operations staff judged that the uncharged method in line side was before carrying out the cutter operation of splice grafting ground at present, and handcart is in test position or maintenance position, and the indicator light of circuit electrification display does not work.If satisfy this two conditions simultaneously, think that then circuit does not have electricity, the ground connection disconnecting link can close.Hence one can see that, and there is bigger potential safety hazard in the mode of this indirect detection circuit energising situation, if electrification display damages, the danger of charged splice grafting ground disconnecting link may appear in operation like this.In addition, this indirect electrical verification mode only is used for the electrical verification of 330kV and above electric equipment.For the 10kV electric equipment, should be with the direct electrical verification of electroscope, and electrification display can only be as a kind of indicative measure.
(3) folding removes the back shrouding that difficulty adopts 12 screw location and installation, needs 3 people to carry out simultaneously during the folding dress. and for the present situation of having only 2 people's operations, so the operation of electrical verification ground connection all is indirect electrical verification.
The utility model content
The utility model is at the deficiencies in the prior art, a kind of improved switch cubicle is provided, its ZSS-10 type switch cubicle cable vault and bus-bar room split setting by being wholely set in the prior art, and set cable vault's door and bus-bar room door respectively accordingly, then during cable vault's maintenance of equipment, only need open cable vault's door and get final product, eliminate brushing up against the potential safety hazard that the charged bus of bus-bar room is caused effectively.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of improved switch cubicle, comprise switch cabinet body, described switch cabinet body comprises secondary chamber, switch handcart chamber, bus-bar room and cable vault, and described bus-bar room and cable vault's split are provided with, and bus-bar room is equipped with the bus-bar room door, and the cable vault then is equipped with cable vault's door.
Further, be connected through the hinge between one side of described cable vault door and the cable vault, and mechanical lock is installed between the inner surface of another side of this cable vault's door and the cable vault, this mechanical lock comprises the pull bar of unblanking, be used to install the unblank base and the lock body of pull bar, described base is installed in the inner surface of cable vault's door, lock body then is installed in the cable vault, and the outer surface of cable vault's door is equipped with operating grip simultaneously, and this operating grip is connected with the pull bar of unblanking by the lock core of five anti-electromagnetic locks.
Further, described base longitudinally is installed on cable vault's door, and lock body then is installed in the bottom, cable vault accordingly.
Further, described five anti-electromagnetic locks adopt ac power supply, and be connected in series with the electrification display normal open switch in the ac power supply circuit of these five anti-electromagnetic locks, when operating grip shake out the position, when the electrification display normal open switch is closed, the ac power supply circuit of five anti-electromagnetic locks is connected.
According to above technical scheme, can realize following beneficial effect:
(1) abandons the back shrouding, switch cubicle cable vault and bus-bar room split are provided with, and set cable vault's door and bus-bar room door respectively accordingly separately, therefore, only open cable vault's door during the cable vault overhaul of the equipments, elimination brushes up against the hidden danger of the charged bus of bus-bar room, when being badly in need of opening the cabinet door, can open the cabinet door within a short period of time.
(2) one five anti-electromagnetic lock will be added between cable vault's door and the operating grip.This five anti-electromagnetic lock power supply adopts ac power supply, and seals in the electrification display normal open switch in its electric power loop, promptly has only when operating grip and is shaking out the position, just can open cable vault's door when the electrification display normal open switch is closed.Abandoned the former directly mode of operation of electrical verification, prevented the possibility of charged splice grafting ground disconnecting link, promptly can directly carry out electrical verification to the cable outlet in the cabinet, can also be clear, intuitively the ground connection disconnecting link is carried out position detection, also prevent the misoperation of charged splice grafting ground disconnecting link simultaneously.
(3) mechanical latching is adopted in the locking of bus-bar room door and cable vault's door, promptly has only when the ground connection disconnecting link to be in when closing gate position, just can open the bus door.For preventing charged unlatching bus-bar room door, the bus-bar room door adopts the special electromagnetic locking.
