Wenzhou Juxing Science and Technology Co., Ltd. was founded on 8th, Nov. 1996. It is a national high-tech enterprise integrating R&D, production, sales, technical consultation and service of electrical contact materials. It is the pioneer of "tri-metal rivets" in the industry, and is the largest t production base for rivet contacts in China.
The company's products include three series of contact materials ...[MORE]
Classification of electrical contacts According to the contact mode, electrical contacts can be divided into the following three types 1) Secure the connection contacts. It refers to the electrical contact that cannot move relative between the contact and connected conductors. Such as bus connector, lead connection of electrical equipment, etc. 2) Sliding contact. The contact mode in which the guide bodies can keep in contact with each other but allow one contact surface to move relative to the other is called sliding contact. For example, the expansion joint of the bus and the brush of the motor are in sliding contact. 3) Breakable contact. If a contact can be closed or opened during normal operation, it is called a breakable contact. Various on
Arc Extinguishing Method of Low Voltage Switchgear Contact 1. Contact resistance of low-voltage switchgear contacts The contact of low-voltage switchgear is an important part of the actuator. The contacts of low-voltage switchgear are used to make and break the circuit, so the required conductivity and thermal conductivity of the contacts are very good. Generally, the contact material is an alloy of copper, silver and nickel, and it is also formed by electroplating silver and nickel on the surface of copper contact. The surface of copper is easy to oxidize. If only copper is used as the contact material, it will increase the contact resistance of the contact, and the loss and temperature of the contact will also increase. Therefore, low voltage with small capacity such as intermediate relay
About relays, contactors, electrical contacts and contacts. I believe all electricians are familiar with electromagnetic relays and contactors. The knowledge about these two kinds of electrical equipment has long been shared by many peers. Today, the author only supplements the contact knowledge of electromagnetic relay and contactor. 电磁继电器和接触器的触点烧损故障是我们工作中经常遇到的问题。这种情况的原因无非是两种可能性：首先，流经触点的负载电流相对较大，非常接近额定值。虽然不超过触头的额定值，但长期使用容易造成触头烧坏；此外，对于上述两种
Widely used in high-power relays, contactors, circuit breakers and switches, etc., and is particularly suitable for T90 relays, car relays
