There is provided incoming line cabinet for electrification display, whether there is or not high pressure criterions；Electromagnetic lock is used for forced blocking incoming line cabinet cable chamber door, prevents high pressure
Personnel's mistakenly entering charged chamber (electromagnetic lock configures compulsive unlocking key, general it is not recommended that using for safety), works as satisfaction when having electricity
1, electrification display has accessory power supply, that is to say that busbar PT output 220V power supply power supplies are normal, 2, incoming line cabinet high pressure without electricity when,
The device can just be unlocked with electrical verification.
However above-mentioned gen-lock device, after incoming line cabinet switch disconnects, entire busbar is without electricity, and for busbar PT without electricity, electrification is aobvious
Show that device does not just have accessory power supply yet, gen-lock device loses normal function, such as whether incoming line cabinet high pressure has electricity at this time, electrification
Display all can not normal electrical verification unlock, under such scheme, can only compulsive unlocking, ordinary device is latched similar to brass padlock here
Function loses original locking effect.Some equipment manufacturers provide power supply using uninterruptible power supply UPS for electrification display, but
UPS discharge times are short, are unable to continued power, cannot meet actual demand.
So the utility model provides a kind of new scheme to solve the problems, such as this.
Utility model content
For the above situation, to overcome the defect of the prior art, a kind of 10kV of being designed to provide of the utility model is opened
Be latched the passive blocking device of incoming line cabinet, have be skillfully constructed, the characteristic of human oriented design, efficiently solve in busbar PT without electricity
When, the problem of passive blocking device of incoming line cabinet can not work normally.
Its technical solution solved is a kind of passive blocking device of 10kV open lockings incoming line cabinet, including high pressure sensor
CGQ, electrification display, electromagnet locking earthing switch and mobile power, the electrification display are powered using direct current 6V, are reserved
There is power supply interface, be delayed certain time power-off after powering on, to ensure having sufficient electrical verification unlocked time；
The electromagnet locking earthing switch power supply is direct current 6V, and electromagnet is latched earthing switch and is grounded mounted on incoming line cabinet
In circuit breaker lock mechanism, mechanism configures compulsive unlocking function, and scribing pressing latching electromagnet bolt can be used to unlock；
The mobile power be DC6V power supplys, mobile power can be it is rechargeable, can also be as TV remote controller pattern
, general dry battery is configured, is conveniently operated, power supply is provided when being unlocked for electrification display electrical verification.
Due to the use of above technical scheme, the utility model has the following advantages that compared with prior art；
1, the design is no longer powered by busbar PT, and power supply is derived from mobile power, and blocking device power supply is reliable.
2, it is locked using electromagnet locking earthing switch substitution ordinary electromagnetic, latching electromagnet reaches the same of ordinary electromagnetic lock
Function saves cost.
