Problems solved by technology

However, the distance between the power supply end and the holding end on the high-voltage generator remains unchanged. When the output voltage is large, the safe distance between the power supply end and the holding end cannot be guaranteed, which reduces safety.

Embodiment 2

[0056] This embodiment provides a high-voltage generator, and compared with Embodiment 1, the structure provided by this embodiment is basically the same as Embodiment 1, and this embodiment will not repeat the same structure as Embodiment 1.

[0057] In this embodiment, the power supply 10 is a rechargeable battery. Preferably, as figure 2 As shown, the high voltage generator also includes a charging module 40 . The charging module 40 includes a charging circuit, the charging circuit is connected to the power supply 10, and the external power supply can charge the power supply 10 through the charging circuit, so that the power supply 10 can be reused and the service life is prolonged.

[0058] Further, the high-voltage generator also includes a switching module 50. When the external power supply charges the power supply 10 through the charging circuit, the switching module 50 can disconnect the power supply 10 and the boost circuit; when the external power supply and the po...

Embodiment 3

[0061] This embodiment also provides a control method, which is applied to the high voltage generator as described in Embodiment 1 or Embodiment 2. The above control methods include:

[0062] Set the preset safety distance according to the detection voltage;

[0063] The distance sensor obtains the actual distance between the handle 3 and the power supply end 30;

[0064] Compare the preset safety distance with the actual distance;

[0065] If the actual distance is not less than the preset safety distance, the distance control switch 60 is turned on, otherwise, the distance control switch 60 is turned off.

[0066] In a control method provided in this embodiment, when the high-voltage generator is working, the distance control switch 60 automatically compares the actual distance between the handle and the power supply terminal 30 detected by the distance sensor with the safety distance required for voltage detection. Controlling the on-off of the boost circuit improves saf...

The safety of the high-voltage generator is improved.

Description

technical field [0001] The invention relates to the technical field of electrical inspection equipment, in particular to a high-voltage generator and a control method. Background technique [0002] According to the requirements of safety regulations, before using the electroscope to inspect the equipment to be tested, the same or similar voltage as that of the equipment to be tested should be applied to the electroscope through other live equipment to check whether the sound and light alarm device of the electroscope is normal. In the actual environment of the site, most of the visible parts of the live equipment are covered with insulating skin, which is inconvenient to check the electroscope, and the voltage of the equipment to be tested is usually relatively high, directly using the electroscope to contact the live equipment may easily cause safety problems such as short circuit , damage live equipment. [0003] At present, the corresponding voltage is provided to the el...
