Abstract

The invention discloses an intelligent contact system, which comprises a contact, wherein the contact comprises a plurality of contact plates and a round panel; the round panel is connected with all contact plates; a hole is formed in the round panel; a universal control device is matched with the contact and is connected with a contact arm through a semi-bolt; the contact is integrally molded by forging and cold pressing; the contact plates evenly surround the contact in a ring and are in a ripple form; and a plurality of contact points are arranged at the positions, with the minimum diameters, of ripples to match with a fixed contact. The intelligent contact system has the beneficial effects that the contact is small in shape and position deviations in the installation process together with the contact arm, high in reliability, high in anti-jamming capability, high in measurement accuracy and convenient to use.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an intelligent contact system. Background technique [0002] The existing contact temperature measurement technology generally adopts the temperature measurement of the contact arm of the circuit breaker or the temperature measurement ring of the static contact, and sends the temperature measurement signal to the acquisition device in the form of wireless transmission. Electric CT power supply or step voltage power supply; these commonly used technologies have poor reliability, weak anti-interference ability, cannot directly measure heat source, and have low measurement accuracy. [0003] Duckbill contacts are usually used in static connection structures, using leaf springs to maintain contact pressure. Due to the use of long strip structures, in order to meet the carrying capacity under high current conditions, the contacts are long, which is not conducive to compact st...
