Intelligent integration high-voltage alternating current contactor

Abstract

The invention discloses an intelligent integration high-voltage alternating current contactor, which comprises a pole column, a main body, a main body controller and a proximitor, wherein the pole column is fixedly connected with the upper top surface of the main body via a lower bolt or nut; the main body controller is embedded into the main body after being arranged in a metal shell; a microprocessor circuit, a serial communication interface circuit, an opening and closing control circuit and a filtering circuit are arranged in the main body controller; the main body controller is connected with the promimitor via a serial communication channel; the connecting ends of the serial communication channel are respectively provided with an electric isolation device; an axial-connection vacuum switching tube and an insulator are arranged in the pole column; a solenoid drive mechanism, an energy consumer and an opening and closing energy consumer which are axially connected are arranged in the main body; the solenoid drive mechanism is connected with a travel detection device connected with the main body controller. The intelligent integration high-voltage alternating current contactor disclosed by the invention has the advantages of high intellectualization and integration degree, complete functions, simple structure, convenience in forming a complete set, easiness in operation maintenance, high reliability, high opening and closing speed, no bounce and high phase control precision, and zero switching can be realized.

Description

technical field [0001] The invention belongs to the technical field of electric power and relates to a contactor used in a power grid, in particular to a highly intelligent and integrated high-voltage AC contactor. Background technique [0002] The existing intelligent high-voltage contactors mainly have unreasonable design of mechanical operating mechanism and electrical control circuit, which leads to unsatisfactory mechanical and electrical characteristics of the most important performance points and closing process of intelligent integration of high-voltage contactors, and cannot realize the ideal " The function of "zero switching" is prone to bouncing during the opening and closing process, which will cause great impact damage to the power grid, load and contactor itself. At the same time, the man-machine connection and online functions are not strong. When more supporting equipment is required.
