Abstract
The utility model provides a live locking detection circuit device for a switch cabinet, consisting of a live induction device, a dual-core cable, an electric encoding lock terminal, and a micro-machine locking key. The live locking detection circuit device is characterized in that one end of the dual-core cable is connected with a pair of contacts of the live induction device in the switch cabinet; the other end of the dual-core cable is connected with a pair of terminals of a micro-machine electric encoding lock; an electric encoding lockhole is arranged in a cabinet door; an electric encoding lock is fixed on the cabinet door; the cabinet door is locked by a micro-machine padlock; and the safety management is carried out on an unlocking program. The live locking detection circuit device has the advantages that when the detecting device detects electricity, a circuit is not conducted, the cabinet door is locked and personnel can not enter a certain compartment to carry out the maintenance operation; only when the detecting device detects that no electricity exists, the circuit is conducted, and the cabinet door is opened and the personnel can carry out the safe maintenance operation under the situation without the electricity.
Description
Technical field:
The utility model belongs to the electric equipment detection control apparatus, specially refer to a kind of do not open the cabinet door can't electrical verification or the charged induction installation electric locking that has of observing unsharp various switch cubicles detect loop apparatus.
Background technology:
In the electrical production security incident, mistakenly entering charged chamber and the accident that takes place is the most common, and the error-proof device of device itself is often only realized certain anti-error function, as do not conform to the ground connection plug-in strip and can not open cabinet door etc., or on door of switch cabinet, install Mechanical ring latch additional, or in switch cubicle the mounting strap electrical induction device, can't identify all under the situation of not opening the cabinet door or clearly watch switch cubicle whether electricity is arranged, thereby bring big security risk and hidden danger for operation and maintenance by charged induction installation.In addition, microcomputer that installs additional on charged display unit of installing on the at present existing switch cubicle or charged induction installation, the cabinet door or Mechanical ring latch are independent mutually, do not interconnect to realize whether having in effective detecting box, the 3rd is because factor such as the awareness of safety of individual persons is not high, operation behaviour is random, can't come the strick precaution personnel arbitrarily to open the cabinet door by technological means, bring the risk of personnel's mistakenly entering charged chamber accident.
Summary of the invention:
In order to solve the safety problem of operating personnel's mistakenly entering charged chamber switch cubicle, the utility model provide a kind of safe and reliable, simple, have electric locking to detect loop apparatus with charged induction installation and micro electronmechanical coding lock is interconnected, can effectively prevent operating personnel's mistakenly entering charged chamber, reduce production accident and take place.
The utility model is achieved through the following technical solutions its goal of the invention.
Switch cubicle has electric locking to detect loop apparatus, constitute by charged induction installation, twin core cable line, electricity coding interlocking terminal, microcomputer padlock key, it is characterized in that: by a twin core cable line, one end is connected on the docking point of the charged induction installation in the switch cubicle, the other end is connected on the pairs of posts of micro electronmechanical coding lock, digs electricity coding lockhole on the cabinet door, fixing electricity coding lock, the cabinet door pins by the microcomputer padlock, by the program of unblanking being carried out the full management of family.
Advantage of the present utility model is: this loop is obstructed when checkout gear has detected electricity, close locker door, personnel can't enter certain and be engaged in the inspection travel operation at interval, has only just conducting of this loop when checkout gear detects the nothing electricity, open the cabinet door, personnel are engaged in safe inspection travel operation under the situation of not having electricity, prevented that effectively personnel's mistakenly entering charged chamber from causing personal injury accidents, have fail safe, applicability, characteristics such as simple to operate, can prevent effectively that operation, maintainer are strayed into electric shock accidents takes place at interval opening the cabinet door without authorization.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model lateral surface structural representations.
In the accompanying drawings, the 1st, door of switch cabinet inboard, the 2nd, electricity coding interlocking terminal, the 3rd, twin core cable line, the 4th, charged induction installation.The 5th, the cabinet door.
Embodiment:
Below in conjunction with drawings and Examples invention is described further.
As shown in the figure, switch cubicle has electric locking to detect loop apparatus, charged induction installation 4, twin core cable line 3, electricity coding interlocking terminal 2, microcomputer padlock key constitute, it is characterized in that: by a twin core cable line 3, one end is connected on the docking point of the charged induction installation 4 in the switch cubicle, the other end is connected on the pairs of posts 2 of micro electronmechanical coding lock, on cabinet door 5, dig electricity coding lockhole 7, fixing electricity coding lock 6, cabinet door 5 pins by microcomputer padlock 8, by the program of unblanking is carried out safety management.
Specific implementation method: 1, electricity coding lock 6 is installed.On door of switch cabinet 5 panels, dig electric coding lockhole, electricity coding lock 6 is inserted from cabinet door 5 outsides, fix electricity coding lock 6 by screw in the switch cabinet panel inboard.2, by twin core cable 3, electricity interlocking terminal 2 one docking points of encoding are connected, fixedly the twin core cable line 3, and cause charged induction installation 4.3, with a docking point of the other end connecting band electrical induction device 4 of twin core cable line 3.4, on outside cabinet door 5, install microcomputer padlock 8 additional.5, the logical condition of unblanking is set.(1) opening the cabinet door lock tool should realize by the microcomputer key, opens the preceding electricity coding that must pass through of lockset and locks 6 checkings; (2) whether passing through of electricity coding lock 6 judged by charged induction installation 4.When in the switch cubicle electricity being arranged, there have electric locking to detect the loop to be obstructed, and the microcomputer key inserts the electricity coding lock 6 in cabinet door 5 outsides, can not be by carrying out proving program, and the cabinet door lock tool is not just opened.When checking was passed through, the microcomputer key was just carried out the operation of opening the cabinet door lock tool.For closing 5 judgements that do not need by above-mentioned this loop of cabinet door, only need to guarantee to get final product in cold standby state at interval, reduced unnecessary logic setting, after judging by said procedure, just can open this lock and carry out this electrical verification, hanging earthing conductor at interval, and carry out service work.
