Abstract

The invention discloses a multi-parameter adjustable operating mechanism based on a dual-coil structure, belonging to the field of a switch apparatus, to solve the problems that there is no test technological reserve for a high-voltage direct current relay at present, and design and verification of different models of relay products are short of analysis theory and evaluation data. The multi-parameter adjustable operating mechanism comprises an electromagnetic system, a contact system, a magnetic quenching system and a base; the magnetic quenching system is arranged at the two sides of the contact system; both the electromagnetic system and the magnetic quenching system are fixed on the base through bolts; a contact clamping mechanism is arranged on the contact system for clamping a movable contact and a static contact; and the electromagnetic system drives the contact system to realize on / off operations of the movable contact and the static contact as a power source. The multi-parameter adjustable operating mechanism is used for an arcing test, provides a test platform for arc characteristic analysis and arc mechanism exploration, and provides a verification platform for design of a relay product acting mechanism and an arc extinguishing system.

Description

technical field [0001] The invention belongs to the field of switching appliances, and in particular relates to an operating mechanism with adjustable multi-parameters based on a double coil structure. Background technique [0002] Relays are the basic products of national economic modernization and communication and electronic information technology equipment systems. In recent years, with the rapid development of science and technology in military and civilian fields such as all-electric aircraft, space stations, electric vehicles, and solar power generation, higher and higher requirements have been placed on their electrical systems, and the power supply capacity has also increased accordingly. The high-voltage DC relay is a control actuator used in the high-voltage DC power supply system to complete the system power distribution and load protection functions. There are already relevant series of products in the application stage in foreign countries, but our country is ...
