[0002] Now XLPE insulated cables are gradually replacing traditional cables in the process of power transmission, but with the aging of XLPE insulated cables, their insulation capacity is gradually degraded, and the traditional DC withstand voltage test cannot reflect XLPE The withstand voltage performance of insulated cables, so now an ultra-low frequency high-voltage generator is produced to test the withstand voltage of XLPE insulated cables through low-frequency high voltage, but the existing ultra-low frequency high-voltage generators are small in size, so they are used Sometimes it is easy to cause the danger of leakage due to the damage of the components in the equipment, which affects the personal safety of the staff

The invention discloses a novel ultra-low-frequency high-voltage generator, which includes a casing, the lower part of the left side wall of the casing is provided with a power supply port, the left and right ends of the power supply port are fixed on the casing through ring-shaped fixing pieces, and the casing's The inner cavity is equipped with a first isolation shell corresponding to the current of the power supply port, and the photoelectric isolator is electrically connected to the photoelectric isolator through the controller. It greatly reduces the possibility of danger for users due to electric leakage and other reasons. The controller is isolated from the internal structure through the second isolation shell, thereby preventing the internal structure from affecting the controller. The third isolation layer is used to block the high voltage generated by the transformer. affect the internal structure. When the internal structure is short-circuited through the first overcurrent protector, the second overcurrent protector and the third overcurrent protector, the circuit can be cut off quickly to prevent safety accidents caused by overcurrent.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a novel ultra-low frequency high-voltage generator. Background technique [0002] At present, XLPE insulated cables are gradually replacing traditional cables in the power transmission process. However, with the aging of XLPE insulated cables, their insulation capacity is gradually degraded. The traditional DC withstand voltage test does not reflect XLPE. The withstand voltage performance of the insulated cable, so now an ultra-low frequency high-voltage generator is produced to test the withstand voltage of the XLPE insulated cable through the low-frequency high voltage, but the existing ultra-low frequency high-voltage generator is used in the At times, it is easy to cause the danger of leakage due to the damage of the components in the equipment, which affects the personal safety of the staff. SUMMARY OF THE INVENTION [0003] The purpose of the present inventi...
