10kV distribution transformer gear position live check device

Abstract

The invention discloses a 10kV distribution transformer gear position live check device, which relates to the technical field of 10kV distribution transformer check. During the operation process of the current 10kV distribution network, power-off check is usually required for the 10kV distribution transformer, the check is complicated and the safety is poor. The 10kV distribution transformer gearposition live check device comprises a detachable insulating rod, a high voltage detector, a low voltage secondary current clamp and a portable distribution transformer gear position check instrument,wherein the high voltage detector is connected with the upper end of the insulating rod, clamping and separation of a high voltage wire are realized through motor control, the high voltage side current of the 10kV transformer is measured and wirelessly transmitted to the portable distribution transformer gear position check instrument, the low voltage secondary current clamp is connected with a low voltage wire at a user side for measuring low voltage current and transmitting the low voltage current to the portable distribution transformer gear position check instrument in a wired mode, checkby a worker is carried out, check on the 10kV distribution transformer is thus completed simply, quickly and accurately, and a basis is provided for distribution transformer gear position adjustment.

Description

technical field [0001] The invention relates to the technical field of 10kV distribution transformer checking, in particular to a 10kV distribution transformer gear live checking device. Background technique [0002] At present, in the operation process of the 10kV distribution network, in order to ensure that the voltage at the end of the line meets the requirements, it is often necessary to check the power failure of the 10kV distribution transformer, so as to realize the adjustment of the distribution transformer gear, so as to ensure the overall performance of the 10kV distribution transformer. Stay on the 10kV standard. [0003] The traditional gear adjustment for 10kV distribution transformers is done through manual checks after power outages. Considering the safety of the staff, power-off measures must be taken before adjusting the gear position. After all the loads on the low-voltage side are disconnected, the high-voltage side drop insurance is opened, the gear cov...
