Abstract
The utility model discloses an anti-misoperation lockout grounding lock. The front end of a ground wire adopts the shape of a rectangular prism, a circular locking hole and a magnet hole for embedding a magnet are formed on the top surface, the back end of the ground wire is cylinder-shaped, in which a grounding copper wire is clamped, a locking sleeve is fixed on the bottom surface of a lock bracket, an electromagnetic lock positioned on the top surface of the lock bracket is clamped in the locking sleeve through penetrating an electromagnetic lock through hole of the lock bracket, and the electromagnetic lock is fixed with the locking sleeve through the lock bracket. When the ground wire is inserted into a ground wire hole, the sensor of the electromagnetic lock aims to the magnet in the magnet hole, and a lock pin of the electromagnetic lock can be inserted into the locking hole of the ground wire through penetrating a lock pin through hole. The anti-misoperation lockout grounding lock has the characteristics that the lock can detect the grounding states of devices, the operation is convenient, the grounding is safe and reliable, and the detecting sensitivity is high.
Description
Technical field
The utility model relates to a kind of grounding lockset that is used for the preventing faulty operation of electric power system system.
Background technology
At present microcomputer anti-error operating system has been widely used in the transformer station, power plant of electric power system.Lockset in the anti-misoperation system mostly is mechanical lock greatly, can be by equipment such as electric or mechanical system locking switch, disconnecting link (cutter), pile and net doors.But mechanical lock can only simply lock, virtual condition that can not checkout equipment, switching lock state that can not detection itself; Lockset hangs on the equipment, and when a plurality of equipment were unblanked simultaneously, lockset mixed easily.Because this type of deficiency uses the microcomputer anti-error operating system of this lockset just to have a serious deficiency, that is: when carrying out on-the-spot switch operation, device physical status is not known by system, does not know the open and-shut mode of lockset yet.All states can only rely on artificial judgement, and the very big possibility of makeing mistakes is arranged, as: just only release and do not have operation carry out next step operation of current device, this situation is become " do-nothing operation ", and consequence is device damage, loss of life or personal injury often; Current device operation back is non-latching, and this situation is become " empty locking ", causes equipment to be in no blocking, in case by malfunction, consequence is also very serious.Use can not checkout equipment virtual condition, the anti-misoperation system of the lockset of switching lock state that can not detection itself can only be finished " five is anti-" function of discounting.
Summary of the invention
For some locksets of solving present anti-misoperation system can not the checkout equipment state problem, the utility model provides a kind of anti-misoperation locking grounding lockset, its technical scheme of taking is:
This lockset comprises ground the end of a thread, locking cover and lock support, the front end of ground the end of a thread is rectangular column type, end face has the magnet opening of circular lock hole and embedded magnet, the rear end of ground the end of a thread is a cylinder type, the inside clamping ground connection copper cash, lock support has the electromagnetic lock via hole, locking cover side has the end of a thread hole squarely, end face has the lock pin via hole, the locking cover is fixed on the bottom surface of lock support, be positioned at the electromagnetic lock via hole that electromagnetic lock on the lock support end face passes lock support and be connected to the locking cover, electromagnetic lock is fixed together by lock support and locking cover simultaneously, when local the end of a thread was inserted in the end of a thread hole, ground, the magnet in the sensor alignment magnet opening of electromagnetic lock, the lock pin of electromagnetic lock can pass in the lock hole that the lock pin via hole is inserted into ground the end of a thread.
Lock support is
Type.
The rear end of ground the end of a thread axially has the ground connection copper cash fixing hole of crimping ground connection copper cash.
The front end of ground the end of a thread is fixed in the end of a thread hole, ground by wing bolt.
The locking cover is by being bolted to the bottom surface of lock support.
This lockset cooperates with the electromagnetic lock of installing thereon, and when the electromagnetic lock locking, lock pin is inserted in the lock hole of ground the end of a thread, thus locking ground the end of a thread.Whether the transducer of electromagnetic lock aims at the magnet in the magnet opening, can detect ground wire and whether be in ground state.
It is online that this lockset can adopt welding manner to be fixed on substation grounding, has characteristics easy to operate, that grounding safety is reliable, detection sensitivity is high.
Description of drawings
Fig. 1 is an external structure of the present utility model;
Fig. 2 in the utility model the structural representation of the end of a thread when being inserted into the end of a thread hole, ground.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, the front end of ground the end of a thread 2 is rectangular column type, and end face has the circular magnet hole 9 of circular lock hole 8 and embedded magnet 10, and the rear end of ground the end of a thread 2 is a cylinder type, by axial ground connection copper cash fixing hole 13 ground connection copper cash 1 tightly is pressed in the end of a thread 2 the insides, ground.Be
The lock support 5 of type has electromagnetic lock via hole 15, locking cover 3 sides have the end of a thread hole 14 squarely, end face has lock pin via hole 16, locking cover 3 is fixed on the bottom surface of lock support 5 by bolt 4, being positioned at electromagnetic lock 6 on lock support 5 end faces passes electromagnetic lock via hole 15 and is stuck in locking cover 3, electromagnetic lock 6 is fixed together by lock support 5 and locking cover 3 simultaneously, and the front end of ground the end of a thread 2 can be fixed in the end of a thread hole, ground 3 by wing bolt 7.
As shown in Figure 2, during the attaching ground wire, ground the end of a thread 2 is inserted in the end of a thread hole, ground 3, the lock pin 11 on the electromagnetic lock 6 stretches out and passes in the lock hole 8 that lock pin via hole 16 is inserted into ground the end of a thread 3, then with electromagnetic lock 6 lockings.At this moment, ground the end of a thread 2 is locked, and the transducer 12 of electromagnetic lock 6 is aimed at the magnet 10 of ground the end of a thread 2, and electromagnetic lock 6 detects ground wire and is in ground state.
When removing ground wire, earlier electromagnetic lock 6 is unblanked, again electromagnetic lock lock pin 11 is pulled out from the lock hole 8 of ground the end of a thread 2.At this moment, ground the end of a thread 2 can be pulled out from the end of a thread hole, ground 14 of locking cover 3, and the magnet 10 of ground the end of a thread 2 departs from the transducer 12 of electromagnetic lock 6, and electromagnetic lock 6 detects ground wire and is in unearthed state.
