Abstract
An isolation change-over switch interlock mechanism belongs to the technical field of combined switch auxiliary apparatuses used for mining. The problem that the utility model aims to solve is to provide the interlock apparatus which can prevent two isolation change-over switches from being simultaneously closed in operation of the isolation change-over switches. The technical scheme employed is that an interlock plate guide post is arranged vertically along a cabinet door of a switch cabinet; a switch interlock plate is arranged along a length direction of the interlock plate guide post; an upper isolation change-over switch shaft and an upper isolation change-over switch support sheet are arranged above the interlock plate guide post; a lower isolation change-over switch support sheet and a lower isolation change-over switch shaft are arranged below the interlock plate guide post; and after the upper isolation change-over switch support sheet and the lower isolation change-over switch support sheet rotate for 75 degrees to 85 degrees to push the switch interlock plate to move along the length direction of the guide post of the interlock plate, the upper isolation change-over switch support sheet and the lower isolation change-over switch support sheet are respectively made to be in a state of being pressed tightly by the switch interlock plate. The utility model is applicable to mining-used combined switch dual power supply inlet wires.
Description
Technical field
A kind of isolation reversing switch mutual interlocking gear, belongs to combined switch for mining servicing unit technical field.
Background technology
In specific electric power system under coal mine, for improving system reliability of operation, especially electric power system is designed to dual power supply, can manually switch to rapidly on another set of power supply when a set of power failure wherein or when unstable, allow another set of power supply move, to ensure the continuous of power supply.But now just there is a kind of possibility, when operation isolation reversing switch, easily mistake is closed a floodgate two isolation reversing switches simultaneously, if two cover inlet wire power phases are inconsistent, power supply short circuit will occur, cause electric power incoming line fault or accident, thus affect colliery underground power supply used continuously and stable.
Utility model content
The interlock of avoiding mistake that two isolation reversing switches are closed a floodgate simultaneously when technical problem to be solved in the utility model is to provide a kind of operation isolation reversing switch.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of isolation reversing switch mutual interlocking gear, comprise isolation reversing switch axle, upper isolation reversing switch support sheet, switch interlock plate, interlock board lead, lower isolation reversing switch support sheet and lower isolation reversing switch axle, described interlock board lead vertically arranges along the cabinet door back side of switch cubicle, described switch interlock plate arranges along interlock board lead length direction, described upper isolation reversing switch axle, upper isolation reversing switch support sheet is arranged on interlock board lead top, and described upper isolation reversing switch axle one end is vertically connected with the upper isolated operation handle in cabinet door front behind the door through the cabinet of switch cubicle, the other end is connected with upper isolation reversing switch support sheet, described lower isolation reversing switch support sheet, lower isolation reversing switch axle is arranged on interlock board lead below, and described lower isolation reversing switch axle one end is vertically connected with the lower isolated operation handle in cabinet door front behind the door through the cabinet of switch cubicle, the other end is connected with lower isolation reversing switch support sheet,
After 75 ° of-85 ° of pull switch interlock boards of described upper isolation reversing switch support sheet rotation move down along interlock board lead length direction, the state of lower isolation reversing switch support sheet in being compressed by switch interlock plate lower end, after promoting switch interlock plate after described lower isolation reversing switch support sheet rotates 75 °-85 ° and moving up along interlock board lead length direction, the state of upper isolation reversing switch support sheet in being compressed by switch interlock plate upper end.
The position of described upper isolation reversing switch support sheet pull switch interlock board is circular-arc, and the position of described lower isolation reversing switch support sheet pull switch interlock board is circular-arc.
The beneficial effect that compared to the prior art the utility model has is: when need to be to the upper isolation reversing switch of switch cubicle, lower isolation reversing switch one of them while carrying out closing operation, for example, when upper isolation reversing switch combined floodgate, the upper isolated operation handle in dynamic circuit connector Over-The-Counter door on the offensive front, upper isolated operation handle drives upper isolation reversing switch axle, upper isolation reversing switch support sheet, upper coupling is along with upper isolated operation handle rotates 75 °-85 °, now going up coupling also drives isolation reversing switch to closing position, because upper switch support sheet pull switch interlock board moves down and makes switch interlock plate lower end kill lower isolation reversing switch support sheet along interlock board lead, lower isolation reversing switch support sheet cannot rotate, again because lower isolation reversing switch support sheet and lower isolation reversing switch axle, lower coupling, lower isolated operation handle interlock, below isolate reversing switch and cannot carry out closing operation, in like manner, if when lower isolation reversing switch is closed a floodgate, because lower switch support sheet pull switch interlock board moves up and makes switch interlock plate upper end kill upper isolation reversing switch support sheet along interlock board lead, upper isolation reversing switch support sheet cannot rotate, also just make isolation reversing switch cannot carry out closing operation,
So on isolate in reversing switch closes a floodgate and also ensured that time isolation reversing switch can be in "on" position, realize the mechanical interlocked of upper isolation reversing switch and lower isolation reversing switch by simple structure and operation, effectively ensure reliability and the fail safe of electric power system dual power supply process, avoided occurring the operation that mistake is closed a floodgate two isolation reversing switches simultaneously.
