Abstract

The invention provides a low-voltage intelligent cost control switch. The switch comprises a cost control switch, wherein the cost control switch is connected with a prepayment electric energy meter,the prepayment electric energy meter is connected with a power supply, the fee control switch comprises a controller, a circuit breaker and a built-in power supply, the controller and the circuit breaker are connected with the built-in power supply, and the built-in power supply and the circuit breaker are connected with the prepayment electric energy meter. The switch is advantaged in that the circuit breaker is used for replacing an external manual switch, manual intervention on closing of the intelligent switch is eliminated, a mechanical motor is used for replacing a magnetic coil, a phenomenon that attraction is not in place due to scrap iron generated when the magnetic coil is attracted is eliminated, and the equipment operation stability is improved; overload protection is achieved,and the probability of equipment burning is reduced; electric charge loss is controlled through the circuit breaker, electricity stealing behaviors are reduced, line loss is reduced, and remarkable economic benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of low-voltage switches, in particular to a low-voltage intelligent fee control switch. Background technique [0002] The traditional way of electrifying the motor well adopts the mode of payment by swiping the card. The user swipes the card to deduct the fee at the terminal of the swiping card. The low-voltage AC contactor closes and the power is turned on. The magnetic coil of the contactor works for a long time, causing the internal coil to heat up and burn out. If the current is too high, the contacts will stick together and form a normally closed state. The user can use electricity without swiping the card; The switch of the object is stuck and the switch is broken to form a normally closed state, and the electricity can be used without swiping the card; because the location of the machine well is located in the field, the fluidity of pouring the ground is large, which brings great troubles to anti-thef...
