Description

Split type electromagnetism program mechanical latching

Technical field:

The utility model belongs to lock technology field, is specially adapted to a kind of split type electromagnetism program mechanical latching on transformer station or the power plant high voltage switchgear.

Background technology:

Along with the application of Control Technique of Microcomputer in transformer station, circuit breaker deciliter is by system controlled by computer in the high voltage switchgear, therefore, the original-pack transformer station that mechanical procedure lock is arranged, procedure lock on its isolating switch can't interrelate with deciliter state of circuit breaker, thereby lost the locking effect, become an outstanding problem so solve system controlled by computer with the connection problem that Mechanically programm locks.And the existing mechanical procedure lock, its complex structure, manual operation is loaded down with trivial details, and, because of being subjected to the restriction of locus, and make the very inconvenience of installation of lock body.

Summary of the invention:

The purpose of this utility model provides a kind of Mechanically programm's latching operation that can make and puts in place, and it is simple in structure, operation is light, easy for installation, the split type flexibly electromagnetism program mechanical latching of unlatching.

Realize that the technical scheme that the purpose of this utility model is taked is: this program locking comprises switch lock, knife switch lock, net door lock, ground connection lock etc., each lock is by lock body, lock shaft, mechanical key is formed, its main feature is: lock body is provided with separable electromagnet and opens and closes key, be provided with straight channel in the lock body, lock shaft is housed in the passage, and the pellet shot from a slingshot hole on the lock shaft is communicated with the lockhole that the plug-in mounting electromagnet opens and closes key, and an end of lock body is provided with the active joint of being convenient to install.

The split type electromagnetism program mechanical latching of making according to such scheme opens and closes key by electromagnet and can make things convenient for freely driving lock shaft, puts in place thereby solved Mechanically programm's control lock operation, and circuit breaker not have disconnection and causes the operating accident of on-load broaching tool lock.Because procedure lock of the present utility model is a kind of indirect electromagnetism program mechanical latching, electromagnet on it opens and closes key and lock body adopts split-type structural, can become electromagnetism key general on the whole transformer station high voltage switchgear, this key can be kept in the key locker in control room, be not subjected to wind wet by the rain and burnt by the sun, all the time be in serviceable condition, and the orderly transmission by original mechanical coding key on the lock body, reach and realize the purpose of unblanking.Characteristics such as that this electromagnetism procedure lock has is simple in structure, be convenient to install, dependable performance is stable, easy to operate, unlatching is flexible.And can satisfy five anti-requirements of power department, thereby promptly anti-error drawing switch, prevent on-load drawing disconnecting link, prevent charged hanging ground-wire, prevent switching on earth wire, prevent that mistakenly entering charged chamber from can effectively stop the generation of misoperation fault.

Utilize accompanying drawing to further describe embodiment of the present utility model below.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Embodiment:

Referring to Fig. 1, this procedure lock comprises switch lock, knife switch lock, the net door lock, ground connection lock etc., each lock all has lock body 1, lock shaft 2, mechanical key 6 is formed, on lock body 1, be provided with separable electromagnet and open and close key 13, be provided with straight channel in the lock body 1, lock shaft 2 is housed in the passage, pellet shot from a slingshot hole on the lock shaft 2 is communicated with the lockhole that electromagnet opens and closes key 13, it is by electromagnet ontology 13-1 that electromagnet opens and closes key 13, switch 11, connecting plate 15, contact 10, back-moving spring 10-1 forms, and wherein, connecting plate 15 is connected the end of electromagnet ontology 13-1 by securing member, be provided with the room in the connecting plate 15, be provided with contact 10 in it, back-moving spring 10-1 be housed, after the energising on the contact, the electromagnet that one end of contact 10 stretches on the lock body 1 opens and closes in the key lockhole, and the other end contacts with drive rod 14 among the electromagnet ontology 13-1.Drive contact 10 motions by the drive rod in the electromagnet 14.In this case, electromagnet ontology 13-1 and switch 11 are known valve control electromagnet assembly, can directly purchase in market.During use, two lead-in wires 12 of electromagnet are connected on the relevant position of control switch auxiliary contact, when switch disconnects, long close point is to connect at the position electric current that closes, aim at and put in the lockhole that is provided with on the lock body 1 by the flexible contact 10 that electromagnet opens and closes in the key, steel ball in the lockhole 9 is flat with pellet shot from a slingshot 8 tops, can easily drive lock shaft 2, after latching operation put in place, electromagnet can be opened and closed key 13 extracts, and carry out the intersection use of mechanical key 6 and electromagnet keying key 13, thereby effectively solved the connection problem of system controlled by computer and procedure lock.One end of lock body 1 is provided with the active joint of being convenient to install 3.This active joint 3 is threaded, and is connected with lock body 1 by pressing plate 1-1, is set with

double nut

4,5 on the joint 3.During installation, lock body 1 is motionless, only needs turn active joint 3 to get final product, and is after turn puts in place that

double nut
