[0007] The beneficial effects of this utility model are as follows: This device is compatible with multiple modules, and the charging and discharging of the module can be controlled by voltage detection. By using voltage detection to control the on and off of the module charging and discharging circuit, the capacitor module can be accurately charged and discharged and the risk of overcharging can be prevented. The capacitor module can be quickly balanced. It is also small in size and easy to carry for after-sales maintenance.

[0008] To achieve precise charging and discharging of the capacitor module and prevent the risk of overcharging, and to achieve rapid voltage equalization of the capacitor module:

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0021] Please see Figures 1 to 2 A portable capacitor mold charging and discharging detection device includes a detection device body 1, a handle 2 fixedly installed on the top surface of the detection device body 1, a support foot 3 fixedly connected to the bottom surface of the detection device body 1, and a connection plug 4 provided on the right side wall of the detection device body 1.

[0022] The left side of the detection device body 1 is provided with a switch 11 and several connection ports 12.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, the internal circuitry of the detection device body 1 consists of a power supply circuit and a control circuit.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the support feet 3 are located at the four corners of the bottom surface of the detection device body 1, and the two support feet 3 near the left end are higher than the two support feet 3 near the right end.

[0025] The working process of this portable capacitor mold charge / discharge detection device is as follows:

[0026] First, place the detection device body 1 stably by tilting it with the support feet 3 on the bottom. Then, connect it to an external power source through the connector plug 4. Power the control circuit through the power supply circuit. Then, insert the connecting wire into the corresponding connector 12 and connect it to the capacitor to be tested. At this time, turn on the switch 11. The detection module measures the actual voltage value of the capacitor module. If there is a voltage shortage, turn on the DC regulated power supply, set the required voltage value of the module, and charge it. The monitoring module will protect it from charging.

[0027] The monitoring module can be set with a voltage range. When the module voltage is less than the set value, the normally open contact closes to charge the module. When the module voltage is greater than the set value, the normally open contact opens, the contactor breaks the circuit, and charging stops. If there is overvoltage, discharge is performed. In this case, the DC regulated power supply needs to be turned off and a resistor is used for discharge. The circuit breaker is opened and disconnected in real time according to the voltage displayed by the monitoring module. This achieves accurate charging and discharging of the capacitor module and prevents the risk of overcharging the capacitor module. It also achieves rapid voltage equalization of the capacitor module. The device is conveniently carried by the user with the top handle 2, making it easy to maintain and test.
