Abstract

The invention relates to a five-prevention interlocking mechanism, which comprises a lower door ground interlocking unit and a load isolation and ground isolation interlocking unit. The lower door ground interlocking unit consists of a door hanging arm plate, a lower door interlocking connection pull rod, an interlocking connector, a crank arm and a lower door interlocking shaft shaft, wherein the door hanging arm plate is connected with the lower end of the lower door interlocking connection pull rod, the upper end of the lower door interlocking connection pull rod is connected with the interlocking connector, the interlocking connector is connected with one end of the crank arm and the other end of the crank arm is connected with the lower door interlocking half shaft. A ground baffle which is arranged in the front of a ground operating shaft is locked or unlocked under the situation that a lower door is not hung or hung on the door hanging arm plate to control the opening/closing of a ground switch and the opened/locked state of the lower door. The load isolation and ground isolation interlocking unit consists of an isolation indicating wheel, a ground indicating wheel, a cam and a camshaft. After an isolating switch and the ground switch are closed, the ground baffle and an isolating baffle are respectively locked in the front of the ground operating shaft and an isolation operating shaft to prevent the ground switch and the isolating switch from being mistakenly operated. The five-prevention interlocking mechanism has the advantages of small size, convenience in installation, simplicity and convenience in operation and high safety and reliability.

Description

A kind of five anti-interlocking devices
Technical field
The present invention relates to high voltage electric equipment door lock, particularly relate to a kind of five anti-interlocking devices.
Background technology
The safe operation of system is always attached great importance in electric power system, but the annual all kinds of accidents always occurring to cause because of electric misoperation, cause unnecessary loss.In order to effectively prevent from running the person and substantial equipment accident that misoperation of electrical equipment causes, China just proposes the requirement of electric equipment " five prevent " as far back as nineteen ninety, and defines the management of error-proof device, operation, design and use principle with the form of regulation.According to the rules, the design principle of error-proof device is: all high voltage electric equipments likely causing misoperation, all should install error-proof device.
Conventional interlock mechanism mostly is lever drive, and operational torque is large, effort, and transmission distance, deviation accumulation is large.The large installation of conventional interlock volume is inconvenient.Five anti-interlocking devices of the good mechanical structure of simple, easy and simple to handle, the easy for installation barrier propterty of a kind of structure are researched and developed for I company spy of this situation.The problems such as the not enough chain inefficacy caused of linkage structure rigidity are structurally avoided in the connection of rigidity, and effectively stop the accident that misoperation causes, this Novel connection lock side case can significantly improve power supply quality.
Summary of the invention
The technical problem to be solved in the present invention is that in order to provide, a kind of structure is simple, easy and simple to handle, five anti-interlocking devices of good, the pure mechanical structure of protective.
The technical scheme adopted is:

Described isolation ground connection interlocking and isolation load interlocking unit, comprise grounded barrier, isolation baffle plate, isolation indicator wheel, ground connection indicator wheel, isolation interlocking catch, switch output board, output toggle arm, cam, camshaft.Isolation indicator wheel connects the driving shaft of isolating switch, and isolation indicator wheel is connected with grounded barrier is sealed, and ground connection indicator wheel connects the driving shaft of earthed switch, ground connection indicator wheel and isolate that baffle plate is sealed to be connected.Described camshaft is connected with the driving shaft of on-load switch, cam is contained on camshaft, and the cam turned is connected with output toggle arm, output toggle arm connecting valve output board one end, the switch output board other end connects isolation interlocking catch, isolation interlocking catch with isolate that baffle plate is sealed is connected.After isolating switch closes a floodgate, isolation indicator wheel twist-lock grounded barrier, grounded barrier gear, now cannot operational grounding switch in ground connection operating axis front.After earthed switch closes a floodgate, ground connection indicator wheel twist-lock isolation baffle plate, isolation baffle plate gear, now cannot disconnecting switch operation in isolated operation axle front; After on-load switch (circuit breaker) closes a floodgate, camshaft band moving cam rotates, knock over cam output toggle arm, output toggle arm drives switch output board to rotate, isolation interlocking catch moves with switch output board, isolate and baffle plate locking after chain catch moves, will to be isolated, isolation baffle plate gear in isolated operation axle front now isolating switch cannot operate.
Feature of the present invention:
1, this interlocking gear volume is little, easy for installation.
2, transmission is apart from short, and deviation accumulation is little.
3, operational torque is little, easy and simple to handle.
4, interlocking strength is good, safe and reliable.
It should be noted that: under the prerequisite not changing principle of the present invention and design, the change made or distortion, all belong to protection scope of the present invention .
