The manual energy storage motor is a kind of energy storage motor protector in the process of operation. To a certain extent, the energy storage motor is prone to increase the wire current and heat and burn out. The main feature is that the CPU is integrated on the PCB. The processor, the power conversion unit, and the current acquisition unit for collecting the current signal of the energy storage motor circuit are used for acquiring a signal acquisition unit for switching the time signal quantity and a control unit for disconnecting or conducting the energy storage motor circuit.
The information collected by the current acquisition unit and the signal acquisition unit of the manual energy storage motor is transmitted to the CPU processor. The CPU processor of the entire product issues an instruction to the control unit according to the information transmitted by the current acquisition unit and the signal acquisition unit. The utility model avoids the overload of the energy storage motor and is disconnected in time so as to protect the energy storage motor.
Manual energy storage motor can greatly reduce the damage rate of energy storage motor to a certain extent, reduce the number of maintenance, reduce equipment maintenance costs, and easy installation. The vacuum circuit breaker is named after its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishment are all high vacuum; it has the advantages of small size, light weight, being suitable for frequent operation and arc extinguishing without maintenance, in the distribution network. The application is more popular.
