Problems solved by technology

[0002] At present, in power grids, railway ground signal control systems, and military submarine equipment, the main equipment for local control and remote communication is mechanical air-type products. Features: a. The contact conduction depends on mechanical pressure, and there is mechanical stagnation. Potential safety hazard of coating wear; b. The exposed contact leaks in the air, and the electric arc sprays out when the motor is controlled locally; the contact is easily corroded, oxidized, and dust enters, resulting in poor connection; c. Realize automatic network control; poor product reliability and safety, low level of automation

example 1

[0022] Depend on Figure 1-2 As shown in the figure, D in the figure is the motor of the operating mechanism, S is the driving part with contact breaking and closing and the circular turntable of permanent magnet steel, B1 and B22 are the built-in duplexes arranged correspondingly on the upper and lower sides of the turntable. The vacuum tube of the contact, the vacuum contact of the vacuum electromagnetic induction switch, the normally closed point is connected to the contactor coil, the contactor is connected to the motor, and the high-voltage switch realizes the opening and closing operation; the state signal of the high-voltage switch passes through the vacuum contact of the electromagnetic induction switch It is transmitted with the PROM module, and the PROM module is connected with the microcomputer monitoring system through the RS485 network cable.

[0023] Working principle: Take the closing of the high-voltage switch as an example. When the high-voltage switch is clos...

Abstract

The magnetic induction vacuum complex intelligent controller comprises the motor, vacuum electromagnetic inductive switch, electric circuit, computer control circuit, and it features in the vacuum electromagnetic induction switch being separated by the drive trigger, absorbed permanent magnetic steel and the round rotor installing it, and the vacuum tubes set up and down the round rotor with complex triggers, the vacuum electro magnetic induction switch vacuum trigger constant closing point connected to the contactor coil, contactor connected to the base, high voltage switch realizing switch open and close operation, with the status signal of the high voltage switch conveyed to the PROM module through the vacuum trigger of the electro magnetic induction switch, with the PROM module connected to the computer monitoring system through the RS485 screen line. It can ensure the safety of the electrified wire netting, with wide application.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment control and signal transmission, and in particular relates to a magnetic induction vacuum dual intelligent controller for local operation and remote monitoring of power transmission and transformation equipment in a power grid. Background technique [0002] At present, in power grids, railway ground signal control systems, and military submarine equipment, the main equipment for local control and remote communication is mechanical air-type products. Features: a. The contact conduction depends on mechanical pressure, and there is mechanical stagnation. Potential safety hazard of coating wear; b. The exposed contact leaks in the air, and the electric arc sprays out when the motor is controlled locally; the contact is easily corroded, oxidized, and dust enters, resulting in poor connection; c. Realize automatic network control; poor product reliability and safe...
