Intelligent controller of high-voltage isolation switch

Abstract

The invention discloses an intelligent controller of a high-voltage isolation switch, which comprises a device shell, wherein the right side of the device shell is connected with a connecting wire; awaterproof sleeve II is arranged at the periphery of the wire inlet; a shell cover is arranged on the front surface of the device shell; an electromagnet is arranged at the upper end in the device shell; a triangular block I is fixed to the middle of the inner side of the device shell; and an insulating block is arranged in the middle of the inner lower end of the device shell. According to the device, the closing and opening work is achieved under the action of an insulating plate, a conducting iron core is arranged in the insulating plate, the conducting iron core is conducted when directlyfacing the two wire joints, the conducting iron core is disconnected when not directly facing the two wire joints, and electric arcs are not generated. The device adopts the electromagnet to drive theinsulating block to move, a magnetic field is generated when the current in a coil in the electromagnet is unstable, the insulating plate is attracted up, and the insulating plate is fixed through the action of the two triangular blocks, so that the insulating plate is prevented from falling to turn on a power supply, and accidents can be prevented.

Description

technical field [0001] The invention relates to the technical field of high-voltage isolating switches, in particular to an intelligent controller for high-voltage isolating switches. Background technique [0002] The high-voltage isolating switch is an important switching device in the electrical system of a power plant and a substation. It needs to be used in conjunction with a high-voltage circuit breaker. Its main function is to ensure the safety of high-voltage electrical appliances and devices during maintenance work. , Putting in load current and breaking short-circuit current can only be used for certain switching operations that do not generate strong arcs, that is to say, it does not have the function of arc extinguishing, and the switching gates will generate arcs during high-voltage transmission, so it is very easy for people to switch. It is easy to get an electric shock due to the existence of the arc, so there is an existing intelligent control of the breaking...
