Abstract

The utility model discloses a controllable switch cabinet lock of telephone wires. A coil of an electromagnetic lock is sequentially connected with a switch, a control module, a capacitor and a rectification filtering module. The input end of the rectification filtering module is connected with a stored program control exchange, and special telephone numbers are preset in the stored program control exchange. A pair of telephone wires output from the stored program control exchange are connected with the rectification filtering module, and the control module is provided with a relay. Operators do not need to carry on a key, and a service man only need to dial a group of telephone numbers preset in the stored program control exchange to open the lock remotely or closely, so that fault treatment time is shortened. The controllable switch cabinet has the advantages of being immediate and convenient to use, simple in structure and reasonable and safe to use.

Description

A kind of telephone wire controllable type Lock for switch cabinet

Technical field

The utility model relates to a kind of lockset, particularly the door lock used of the high-tension switch cabinet in the high voltage switchgear equipment.

Background technology

At present, the switchboard door lock in the high voltage switchgear equipment commonly used has mechanical procedure lock and electromagnetic lock etc., and these locks all have lock core, bolt structure; Thereby Mechanically programm's lock drives lock core rotation drive locking bolt through the program key and moves; Realize the opening and closing of switchboard door, its defective is, it is key operated operating personnel to carry program; When reality is used; Operating personnel owing to neglecting the place of forgetting key, when urgent need is keeped in repair fault, operating personnel incur loss through delay the handling failure time because of the look round for key phenomenon often occurs through regular meeting.Coil and electromagnetic core are installed in the electromagnetic lock; Behind coil electricity, but after the electromagnetic core adhesive to locking bolt elder generation release shooting the lock-bolt, its defective is: in case when having fault to take place; Operating personnel at first will get into master control room; Electromagnetic lock is carried out by dedicated program software on the computer limit after the electric operation, open electromagnetic lock to the scene again, this process can be incured loss through delay the time of handling failure.Even electromagnetic lock is equipped with special-purpose emergency release key, but this emergency release key is similar to the key of Mechanically programm's lock, equal delay handling failure time.

Summary of the invention

The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, provide a kind of can Long-distance Control or the telephone wire controllable type Lock for switch cabinet opened of dialing nearby.

The technical scheme that the utility model adopts is: have electromagnetic lock, coil is arranged in the electromagnetic lock, the coil of electromagnetic lock connects switch, control module, electric capacity and rectification filtering module successively; The input of rectification filtering module connects programme-controlled exchange, is provided with dedicated phone number in the programme-controlled exchange in advance; The pair of telephone lines of programme-controlled exchange output connects rectification filtering module; Control module has relay.

The beneficial effect of the utility model is: operating personnel need not to carry key; In case break down, when command centre went to rush to repair arrangement maintenance personal nearby, the maintenance personal only need dial the telephone number of one group of programme-controlled exchange special settings and just can unblank long-range or nearby; Solve at present because of not with key can't handling failure problem; Shorten the time of troubleshooting, had the characteristics of instantaneity, convenience, and simple and reasonable for structure, safe in utilization.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain;

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

Among the figure: 1. programme-controlled exchange; 2. rectification filtering module; 3. electric capacity; 4. control module; 5. switch, 6. electromagnetic lock.

The specific embodiment

Referring to Fig. 1, the utility model adopts the structure of electromagnetic lock 6 commonly used, in the electromagnetic lock 6 coil is arranged, and the coil of electromagnetic lock 6 connects switch 5, control module 4, electric capacity 3, rectification filtering module 2 successively.The input of rectification filtering module 2 connects programme-controlled exchange 1, has established dedicated phone number in the programme-controlled exchange 1 in advance, by the pair of telephone lines connection rectification filtering module 2 of programme-controlled exchange 1 output.Have relay in the control module 4, control and trigger switch 5 make electromagnetic lock 6 actions, can operate the electromagnetism locking bolt.

The utility model makes it carry suitable alternating current for rectification filtering module 2 through programme-controlled exchange or group's switch of dialing with action telecommunication bureau, accomplishes the entire exercise program.When the unfailing service state, the pair of telephone lines between programme-controlled exchange 1 and the rectification filtering module 2 is in holding state, and that it passes through is direct current 48V; When fault need realize unblanking to electromagnetic lock 6; Put through the dedicated phone number that programme-controlled exchange 1 is preset with mobile phone or landline telephone, at this moment the direct current on the telephone wire is just imported the 24V alternating current by programme-controlled exchange 1 automatically, just becomes the 24+48=72V alternating current; This 72V alternating current directly inputs to rectification filtering module 2; The actuating of relay in rectification filtering module 2 drive control modules 4, it is electric that electromagnetic lock 6 coils are got, and just can open electromagnetic lock 6.

Claims
