Arc Light Protection Product
Product Profile
The harm degree of arc fault depends on the arc current and cutting time, and the energy generated by arc increases rapidly with I2t exponentially. Only the total resection time is less than 80ms, can make the equipment not damaged, the total resection time is greater than 100ms, will cause different degrees of damage to the equipment.
BAP600 series arc protection is based on the main action of the fault generated by two factors: arc and current signal, when the detection of arc and current rising signal at the same time to send a trip command. The arc light protection system is divided into three parts: the main arc light protection unit, the auxiliary arc light protection cell and the arc light sensor.
Arc Light Main Unit BAP601:
The main unit contains current detection and circuit breaker failure protection, which detects short-circuit current and action information from arc light sensors, and processes and judges the collected data, and issues a blocking command to remove the fault when the blocking conditions are met. The circuit breaker cannot be cut on the in line
When debugging, it activates the circuit breaker failure protection logic, issuing a blocking command to the secondary circuit breaker to remove the fault. In addition, the main unit provides location and temperature alarm information for arc light failure points based on the arc light sensor action information transmitted by the auxiliary unit and the temperature measured by the temperature sensor.
Arc Extension Unit BAP603:
When arc failure occurs in the system, the auxiliary unit collects the action information from the electric arc sensor and transmits it to the main unit. The address number of the auxiliary and arc sensor is displayed on the main unit, which facilitates the timely and accurate fault location of the switchboard and provides information for maintenance.
Arc light sensor BAP01 / BAP02:
A arc-light sensor dedicated to mother-line protection is installed in the mother-line room of the switchboard, which acts as a light sensing element to detect the sudden increase in the light intensity in the event of arc-light failure and converts the light signal into an electrical current signal to the auxiliary unit.
BAP600 series arc protection comprehensively improves the concept of traditional mother line protection, improves the speed of fault handling, can effectively solve the damage caused by short circuit fault arc protection, reduces equipment maintenance and personnel casualties, and improves the safety and economic efficiency of power systems.
Product Features:
The principle is simple: by detecting arc light, combining overcurrent to shut down the lock
Simple structure:
flexible configuration and adaptability
Fast and reliable action: protection action time of 12 ms by detecting the arc light signal
Circuit breaker failure protection: When the main circuit breaker resists, the breaker is sent a blocking instruction to jump on the first circuit breaker, improving the security of the protection system.
