Relay contact combinations for inductive and capacitive loads

Abstract

Relay contact combinations suitable for inductive and capacitive loads, involving electrical contact materials. Provides a relay contact combination that can solve the problem of contact bonding and failure during the relay action process, and can be combined according to the size of the electronic work function and the complementary performance advantages to adapt to inductive and capacitive loads. The relay contact combination adapted to inductive and capacitive loads is a combination of dynamic and static contacts using different composite materials, and the composite materials include AgSnO 2 , AgCdO, AgZn, AgNi, etc. The combination can choose the electrical contact combination with different electronic energy according to the requirements of the electronic work function, and the static and dynamic contacts of the relay. It effectively improves the application characteristics of the original relay, produces complementary effects and new contact electric effects; and effectively solves the bonding problem of the relay, greatly prolonging the service life of the relay under inductive and capacitive load conditions. Adapt to various relays, according to the use requirements of various relays, select different material contacts for combination.

Description

technical field [0001] The invention relates to electrical contact materials, in particular to a relay contact combination suitable for inductive and capacitive loads. Background technique [0002] The contact point is the most important component of the relay. As the core component of the electronic device, the contact point is widely used in production and life, and the contact material is the main factor restricting the performance of the contact. Pay attention to the development and application of electrical contact materials. [0003] With industrial automation, intelligent products, and the popular use of a large number of motors and LED lights, relays are not suitable for inductive and capacitive loads from the original case of mainly adapting to resistive loads, and arc ablation will occur when the relay contacts act. The contacts are bonded and the relay fails to work, which is the fatal problem of the relay. At present, despite adopting zero-crossing circuits, in...
