Abstract
The utility model relates a Siemens ring network power supply grounding switch locking device, which comprises a mounting board and an electromagnet. The mounting board is arranged on an inlet unit operating mechanism support board, and the electromagnet is fixed onto the mounting board. The device is capable of locking operation of a grounding switch when a high-voltage inlet cable is live, preventing live false close of the grounding switch effectively, and preventing high-voltage grounding short circuit caused by misoperation. When the inlet cable is not live, operational locking for the grounding switch is released and normal operation of the grounding switch cannot be affected.
Description
Technical field
The utility model relates to a kind of Siemens ring main unit earthed switch locking device, relates to Siemens's ring main unit electric power incoming line unit earthed switch operation, prevents that the charged mistiming splice grafting of wire inlet unit high-tension cable ground switch from causing the high-voltage earthing short circuit accident.
Background technology
Continuous development along with technology, country is more and more higher to the requirement of power grid security, in existing Siemens ring main unit, wire inlet unit, outlet unit all are equipped with three position on-load switches, switch has three kinds of states: combined floodgate, separating brake, ground connection, between three kinds of states strict latching relation is arranged, satisfy the requirement of high pressure five-defence block.For the outlet unit, have only the outlet on-load switch to be in "on" position, cable just can be charged; And wire inlet unit, the inlet wire high-tension cable whether charged whether send electricity relevant with higher level's power supply unit, irrelevant with inlet wire on-load switch state of living in.So Siemens looped network cabinet wire unit exists potential safety hazard, when on-load switch is in gate-dividing state, when the inlet wire high-tension cable is charged, can splice grafting ground switch and cause the high-voltage earthing accident.
Summary of the invention
The purpose of this utility model is to provide a kind of Siemens ring main unit earthed switch locking device, this device is installed in the looped network cabinet wire unit operations mechanism, when the inlet wire high-tension cable is charged, pin the operating mechanism interlock plate, make interlock plate can't slide into the earthed switch operative position, prevent that earthed switch from closing by mistake, effectively avoided the hidden danger of charged splice grafting ground switch.
The purpose of this utility model is achieved in that this Siemens's ring main unit earthed switch locking device comprises mounting panel, electromagnet.Mounting panel is installed on the wire inlet unit operating mechanism support plate, and electromagnet is installed on the mounting panel.Electromagnet controlling power supply is taken from ring main unit electric operating cabinet, and the power supply switching is controlled by the high-voltage charge display device auxiliary contact.
When the inlet wire cable was charged, electromagnet discharged, and lock core stretches out, and blocks the operating mechanism interlock plate, and interlock plate can not slide into the earthed switch operative position, just can not splice grafting ground switch, prevented the charged splice grafting ground switch that misses.When the inlet wire cable does not have electricity, the electromagnet action, the lock core withdrawal discharges interlock plate, and interlock plate slidably arrives the earthed switch operative position, but the normal running earthed switch.By the constraint interlock plate, reach the purpose of locking earthed switch operation.
Below in conjunction with the drawings and the specific embodiments the utility model is further described, but structure of the present utility model is not limited to shown in the accompanying drawing.
