It is suitable for indoor 3-12kV three-phase AC 50(60) Hz power systems to be used in conjunction with various types of high-voltage switch cabinets. It can also be used as grounding for high-voltage electrical equipment maintenance. The main structure, the grounding switch, is composed of a bracket, a grounding knife assembly, a static contact, a sensor, a shaft, an arm, a compression spring, a conductive sleeve, and a soft connection.
When the operating mechanism is operated to close the grounding switch, it acts as a torque to make the main shaft overcome the resistance torque. Drive the crank arm to rotate in the closing direction, and make the operating lever on the grounding knife pass through the dead point of the compression spring, and the compression spring releases energy. Make the earthing switch close quickly in the closed position. The grounding knife on the grounding knife assembly is in a firm and reliable contact with the flange portion (knife edge) of the static contact through the disc spring.
When the torque is applied, the main shaft overcomes the main torque and the spring force drives the arm to rotate in the direction of opening, and makes the grounding knife pressure spring pass through.
An indoor high voltage electric grounding switch consists of a motor, a driving device, an electric air control device, as well as the main shaft of the grounding switch.
According to the different requirements of the installation location, the earthing switch is divided into two types: the earthing switch for maintenance (ES) and the earthing switch for fault fast closing earthing switch(FES).
The FES fast earthing switch (FES) has the ability to close short-circuit current, and open and close induced current, so it is an important protection device during maintenance. It’s also operated by an electric spring mechanism. The fault earthing switch is suitable for the grounding switch
Below are common questions and answers that are asked about circuit breakers and disconnect switches.
Unlike a circuit breaker, a disconnector switch cannot suppress electric arcs which occur when conductors carrying high currents are electrically interrupted.
Unlike a circuit breaker, a switch does not provide any form of protection. All you need to ensure that your switch has is the capability to carry the maximum load without failing. The purpose of a main switch to a circuit breaker is different. A main switch does not have to be a circuit breaker.
A switchgear is used to switch, isolate, protect, and control electrical equipment. It regulates current changes, load faults, protects users during maintenance, etc. A switchgear is made up of four major components. They are: load break switch, disconnector, disconnector switch, and circuit breaker. These four components have their distinct functions, ensuring that electrical equipment functions properly.
These components have an overall responsibility of ensuring safety in electrical engineering, but they have their distinct functions. As a high voltage disconnect switch manufacturer with vast knowledge about electrical equipment, we will be discussing with you the difference between these four components – load break switch vs disconnector vs disconnect switch vs circuit breaker.
Medium-voltage switchgear is a crucial component in electric power systems, operating in the range of 1KV to 75KV. It plays a vital role in controlling, protecting, and isolating electrical equipment, including motors, generators, feeder circuits, and transmission and distribution lines. The switchgear incorporates electrical disconnect switches, fuses, or circuit breakers, ensuring the reliability of electricity supply by enabling safe maintenance work and swiftly clearing faults downstream. Its significance in power distribution makes it a key element in ensuring a stable and efficient electrical infrastructure.
Vacuum Circuit Breaker (VCB) is a type of circuit breaker that utilizes vacuum as the arc extinction medium. The fixed and moving contacts are enclosed in a permanently sealed vacuum interrupter. When the contacts are separated in high vacuum, the arc is extinguished. VCB is commonly used for medium voltage applications, ranging from 11 KV to 33 KV. It is known for its reliable arc quenching properties and environmentally friendly operation.
