Product Description

Timetric 24Kv Pole Mounted Vacuum Circuit Breaker Introduction

24 Kv Pole Mounted Vacuum Circuit Breaker With the continuous development of China's economy, the structure and load characteristics of power grid are increasingly complex. In order to protect equipment and personal safety, higher requirements are put forward for the safety and reliability of power supply. Before July 2016, the most common circuit safety device was the circuit breaker. It is a kind of manual switch function, and can automatically carry out voltage loss, undervoltage, overload and short circuit protection of electrical appliances. When the device occurs serious overload or short circuit and undervoltage fault can automatically cut off the circuit. Outdoor high-voltage vacuum circuit breakers are exposed outdoors for a long time. In rainy seasons, moisture in the air is easy to enter the circuit breaker and slowly accumulate, forming water droplets, short-circuited the circuit breaker, and affecting the normal operation and service life of the circuit breaker.
