JN15-12 indoor high voltage grounding switch

/BB[]
1. Overview
-Type indoor high-voltage grounding switch is an advanced product developed by integrating the latest technology of grounding switches at home and abroad. After a comprehensive assessment, its performance meets the requirements of the "AC High Voltage Isolating Switch and Grounding Switch" and is suitable for AC power systems of kilovolts and below. It can be used with various types of high-voltage switch cabinets for grounding protection.
Advanced design, reliable technical performance, simple structure, easy installation, and quick opening and closing capabilities.
2. Main structure
The grounding switch consists of a bracket, a grounding knife assembly, a static contact, a sensor, a shaft, a lever, a compression spring, a conductive sleeve, and a soft connection. Note: The bracket is made of thin steel plates that are bent and welded into parts, and the rest are assembled parts.
3. Working Principle
When the operating mechanism is operated to close the grounding switch, the main shaft overcomes the resistance torque as a moment, drives the arm to rotate in the closing direction, and causes the joystick on the grounding knife to pass through The compression spring dead center, the compression spring releases energy, causing the grounding switch to close quickly, in the closing position. The grounding knife on the grounding knife assembly contacts firmly and reliably through the disc spring and the flange part (knife edge) of the static contact.
During the opening operation, the applied torque causes the main shaft to overcome the main torque and the spring force, drives the arm to rotate in the opening direction, and causes the grounding knife compression spring to pass the dead center, and the compression spring ends to store energy in preparation for the next closing. brake.
The grounding switch and closing speed have nothing to do with human operating speed.
