The invention relates to a surge suppressing and arc extinguishing device which comprises a contactor. The contactor comprises three groups of bearing contacts, supports and inlet and outlet wire fixing bases; each group of bearing contact comprises a movable contact and a static contact; the three movable contacts are fixed on the corresponding supports; each inlet and outlet wire fixing base is provided with a connecting plate; and the three static contacts are fixed on the corresponding supports. The surge suppressing and arc extinguishing device further comprises suppressing and arc-extinguishing contacts, resistor current limiting wires and fuse wires; the suppressing and arc-extinguishing contacts comprise suppressing movable contacts and suppressing static contacts; the suppressing movable contacts are fixed on the support; the suppressing static contacts are fixed on the inlet and outlet wire fixing bases; the inlet and outlet wire fixing bases are provided with inner cavities; the resistor current limiting wires are arranged in the inner cavities of the inlet and outlet wire fixing bases; the end openings of the inner cavities are provided with cover plates; the bearing contacts, the fuse wires, the resistor current limiting wires and the suppressing and arc-extinguishing contacts form a parallel circuit; and the opening distance of the suppressing and arc-extinguishing contacts is less than the opening distance of the bearing contacts. The surge suppressing and arc extinguishing device has the comprehensive function of suppressing the surge, extinguishing the arc and bearing the current. The connecting and disconnecting capacity of the contacts is improved, and the service life of the product is prolonged.
Description
Technical field [0001] The invention involves a basic electrical component in the field of electrical technology, especially a contacifier inhibitory wave extinguishing device. Background technique [0002] As the core component of the contact and disconnect circuit of the contact system, it is increasingly valued by people. The setting of the contact structure design, material selection, and arc extinguishing system has a important impact on the performance of the contact device products.The contact form of the contactor mainly includes a double -break point direct -motion, single break -point pattern, etc. In order to reduce the impact of the surge current on the contact, cause the contact welding, and the contactor configuration to suppress the flowing device. [0003] In the currently used switching capacitor contactor, the inhibitory rush device is the top of the contact device at the top of the contact device, and the external resistance restriction streamlines to inhibit t...
