1. leakage circuit breaker industry overview

Definition and Classification of 1.1 Leakage Circuit Breaker

漏电断路器（Earth Leakage Circuit Breaker, ELCB for short）It is an electrical device used to protect personal safety and equipment safety. Its main function is to cut off the power supply line in time when the equipment has leakage failure and when there is a fatal danger of personal electric shock protection, so as to prevent the accident from expanding.. Leakage circuit breaker with overload and short circuit protection function, can be used to protect the line or motor overload and short circuit, orUsed for infrequent switching start-up of the line under normal conditions。

According to the different detection principles, leakage circuit breakers are mainly divided into two types: voltage type and current type。

Voltage leakage circuit breaker (Voltage Earth Leakage Circuit Breaker, VELCB for short) is a device that uses the pressure difference between the ground line and the neutral line to detect leakage. When the pressure difference between the ground line and the neutral line exceeds the set value, the circuit breaker will be triggered。

Current type leakage circuit breaker (Current Earth Leakage Circuit Breaker, CELCB for short) is a device that uses a zero-sequence transformer to detect leakage. When the current imbalance between the supply and return lines exceeds the set value, the circuit breaker will be triggered。

During this period, the earliest leakage protection device-grounding relay (Ground Relay), the principle is to use the zero sequence magnetic flux generated by the ground fault to drive the relay action.

20th century20Years30With the complexity of the power system and the diversification of electrical equipment, the protection range and sensitivity of the grounding relay can no longer meet the needs. During this period, the first generation of leakage circuit breakers-voltage leakage circuit breakers (VELCB), the principle is to use the voltage difference between the ground line and the neutral line to detect leakage.

20th century40Years50With the high voltage and large capacity of power system, the protection effect of voltage leakage circuit breaker is limited. During this period, the second generation of leakage circuit breakers-current leakage circuit breakers (CELCB), the principle is to use a zero-sequence transformer to detect leakage.

20th century60Years70With the development and application of electronic technology, the performance of leakage circuit breakers has been significantly improved. During this period, the third generation of leakage circuit breakers-intelligent leakage circuit breakers (Intelligent Earth Leakage Circuit Breaker, shortIELCB), the principle is to use a microprocessor to control the action of the circuit breaker, with automatic diagnosis, automatic reset, automatic test and other functions.

20th century80With the development and application of information technology, the function of leakage circuit breaker has been further expanded. During this period, the fourth generation of leakage circuit breakers-network leakage circuit breakers (Network Earth Leakage Circuit Breaker, shortNELCB), the principle is to use communication technology to connect the circuit breaker with the monitoring system to realize remote control, fault diagnosis, data collection and other functions.
