A Brief Introduction to WIFI Circuit Breaker

WIFI circuit breaker is a new circuit breaker secondary system built with microelectronics, computer technology and sensors. Its main feature is that the execution unit is composed of electric power technology and digital control device, which replaces the auxiliary switch and auxiliary relay of the conventional mechanical structure.

The working process of WIFI circuit breaker

When the system fails, the relay protection device sends out the opening signal or the operator sends out the operation signal, the automatic reclosing electric protector has high breaking capacity, and the breaking current can reach 65KA, ensuring that the circuit breaker (protector) is running under heavy load. The reliability of breaking first starts the intelligent identification module, judges the current working conditions of the circuit breaker, sends out different quantitative control information to the adjustment device and automatically adjusts the parameters of the operating mechanism to obtain the movement suitable for the current working state of the system. feature, and then actuate the circuit breaker.

What are the characteristics of WIFI circuit breaker

• Long service life: After adopting the intelligent circuit breaker technology, for non-faulty operations, the circuit breaker can be disconnected at a lower speed, reducing the impact force and mechanical wear when the circuit breaker is disconnected, thereby improving the circuit breaker. The service life can achieve better economic and social benefits in engineering.

• The reclosing of the WIFI circuit breaker can be performed multiple times: the traditional reclosing adopts the reclosing relay. During normal operation, the capacitor of the reclosing relay is charged. Avoid the adverse effects caused by the speed of the handle in the automatic closing and opening of the circuit breaker, so as to prolong the instantaneous discharge of the capacitor of the product to achieve the purpose of reclosing. The gate can only be done once.

• Realize phased closing: reduce the overvoltage of closing operation, cancel the closing resistance, the product has all the functions of air switch and leakage switch, and has fault protection, identification and detection functions such as leakage, short circuit, overcurrent, overvoltage, low voltage, etc. Further improvement Reliability: realize the phase selection opening, control the actual arcing time, so that the arcing time of the circuit breaker is controlled at a phase angle that is more conducive to arcing, and is not limited by the system arcing time difference, thereby improving the actual breaking capacity of the circuit breaker.

Wide application of WIFI circuit breaker

Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overload or short-circuit and under-voltage faults, they can automatically cut off the circuit. Its function is equivalent to a fuse switch. Combination with overheating and underheating relay, etc. Moreover, it is generally not necessary to change the components after breaking the fault current. It has been widely used.
