Abstract
The utility model relates to a protecting device of a high-pressure switch cabinet, namely, an additionally-mounted latching lock of a high-pressure cabinet. The latching lock comprises the high-pressure cabinet, wherein a grounding switch is mounted in the high-pressure cabinet; a rotatable slat-shaped lock nose and a square tube-shaped lock nose fixing body are additionally mounted at the position in which the grounding switch of the high-pressure cabinet operates a latching lock baffle plate to act; lock holes are respectively formed in the slat-shaped lock nose and the square tube-shaped lock nose fixing body; and a grounding knife-switch operating mechanism is arranged at the lower cabinet, and a cabinet door and a switch operating mechanism are in a mechanical interlocking mode, so that a grounding knife-switch can be switched off only when the switch cabinet door is opened and a handcart switch is pulled to an overhauling position, and the grounding knife-switch is prevented from being switched off under an electrifying condition. When the latching lock is in normal running, a grounding false operation preventing device can close the latching lock reliably, and an operating hole of the grounding knife-switch is closed reliably when the switch is in a working position, so that the probability that the grounding knife-switch is switched off under the electrifying condition is avoided. Therefore, the accident caused by switching off the grounding knife-switch under the electrifying condition is prevented. In addition, the lower cabinet can be opened only when the grounding knife-switch is switched on, so that the accident of electric shock of a person is avoided. As a result, the personal safety of an operator is ensured.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet protector, and namely high-voltage board installs locking additional.
Background technology
In the prior art, usually the power switch cabinet cable joint is without grounding switch, like this during site examining and repairing the operations staff to install temporary ground wire very difficult, and very easily cause the electrification fault in the installing process.Anti-misoperation locking device is the visual plant that power plant and electric substation prevent misoperation, good reliably anti-misoperation locking device is the important guarantee of personal safety, electrical network and device security, how to guarantee the reliability of error-proof device, stop the pernicious misoperation fault of charged co-grounding switch, make it satisfy day-to-day operation and safeguard and the overhaul of the equipments requirement, particularly important to safety in production.
The utility model content
The purpose of this utility model is to provide a kind of for above-mentioned deficiency to install locking additional at grounding switch operation locking baffle plate, avoids charged and generation grounding switch, and the high-voltage board of avoiding simultaneously the operations staff to install temporary ground wire generation injury accident installs locking additional.
Technical solution of the present utility model is: high-voltage board installs locking additional, comprises high-voltage board, and earthed switch is housed in the high-voltage board.Install rotatable tabular lock nose at high-voltage board earthed switch operation locking baffle plate place additional and be fixed with square tube type lock nose fixed body, on the tabular lock nose of bar lockhole is arranged, on the square tube type lock nose fixed body lockhole is arranged also.
The utility model has the advantages that: 1, this lock has forced the operations staff according to predetermined simulated operating procedure, thereby avoids misoperation, and is anti-error safe and reliable.2, the grounding switch operating mechanism is at lower cabinet, and cabinet door and switch operating mechanism are mechanical interlocked, and after only having cabinet door to open and moving wheelbarrow switch to the maintenance position, the grounding switch that can close has satisfied preventing that the charged co-grounding switch accident from occuring.When 3, normally moving, the reliably locking of ground connection error-proof device, switch is when the service position, and the grounding switch handle hole is reliably sealed, and has stopped the possibility of charged co-grounding switch, has satisfied the accident that prevents " charged co-grounding switch " and has occured.4, only have grounding switch after closing, lower cabinet can be opened, and has satisfied the forced blocking requirement of " preventing mistakenly entering charged chamber ", has prevented the accident of human electric shock, guarantees operating personnel's personal safety.
Below in conjunction with accompanying drawing execution mode of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Referring to Fig. 1, high-voltage board installs locking additional and comprises high-voltage board 4, in the high-voltage board 4 earthed switch is housed, install rotatable tabular lock nose 2 at high-voltage board 4 earthed switch operation locking baffle plate places additional and be fixed with square tube type lock nose fixed body 3 (one section square tube, lockhole is arranged in the middle of the top and bottom, the mouth of pipe towards about, figure is slightly), on the tabular lock nose 2 of bar lockhole is arranged, on the square tube type lock nose fixed body 3 lockhole is arranged also.Padlock 1 dead bolt passes lockhole, by padlock 1 locking.Take from padlock 1 after unblanking, can the tabular lock nose 2 of rotation strip, to realize the control earthed switch.
Claims (1)
1. a high-voltage board installs locking additional, comprise high-voltage board (4), high-voltage board is equipped with earthed switch in (4), it is characterized in that installing rotatable tabular lock nose (2) additional at earthed switch operation locking baffle plate place and being fixed with square tube type lock nose fixed body (3), on the tabular lock nose of bar (2) lockhole is arranged, on the square tube type lock nose fixed body (3) lockhole is arranged also.
