An insulating rod voltage induction automatic disconnection device and its application method

Abstract

The invention discloses an insulating bar voltage induction auto-disconnection device. Safety problems, for example, a common insulating bar can be easily used beyond a voltage class, and the distance between the top end of the bar and a live wire is smaller than the safety distance due to maloperation, are solved. The device comprises a device A (10) and a device B (11). An electromagnetic main switch (1) is used for controlling energization of an electromagnetic coil b (5) of the device B and an electromagnetic coil a (7), wherein the electromagnetic coil a (7) in the upper part is powered by a power supply connector (6) between the device A and the device B. The electromagnetic coil b (5) and the electromagnetic coil a (7) are mutually attracted and connected due to opposite polarities, and the electromagnetic coil b (5) and the electromagnetic coil a (7) are firmly connected through buckling devices (3) and (4). The upper and lower parts of the device are fixed at the ends of the bar respectively. When a voltage inductor (12) senses a dangerous voltage, a current reversing switch (2) is automatically switched in order to reverse the polarity of the electromagnetic coil b (5) of the device B (11), so that the function of automatically separating the device B (11) from the buckling device (3) and the device A (10) through repulsion of magnetic poles is achieved.

Description

technical field [0001] The invention relates to the design field of power system protection devices, in particular to a voltage-sensing automatic disconnection device for insulating rods and a method for using the same. Background technique [0002] When working in high-voltage places such as substations and booster stations, it is necessary to use insulating rods to assist the work, help the instrument to reach a suitable height and achieve a safe insulation effect. When using insulating rods on site, due to the dense wiring arrangement in the workplace, different voltage levels, and potential misoperations will lead to wrong use of insulating rods, resulting in the top of the rod exceeding the safe range and posing a threat of electric shock. This kind of ordinary insulating rod is easy to use beyond the voltage level, and misuse causes the distance between the top of the rod and the live wire to be less than the safe distance, which not only has potential safety hazards, ...
