Electric power transformer field calibration vehicle

Abstract

The invention relates to an electric power transformer field calibration vehicle, which comprises a control chamber and an equipment bay; the equipment bay comprises an integral rack transversely arranged on the front part thereof, various current transformer calibrating equipment and measuring and controlling devices, a high-voltage calibrating device arranged in the middle part of the equipment bay in a liftable way; the top part of the vehicle body is provided with a translational electric sunroof, the high-voltage calibrating device passes through the translational electric sunroof in a controllable way and exposes out of the top of the vehicle so as to complete the calibration of a voltage transformer under high voltage. The invention combines the electric power transformer field calibrating device with the modified special vehicle, thus forming a mobile field calibration vehicle; and when in field calibration, only the corresponding equipment is output and led out of the top of the vehicle, field wiring can be conducted, thus avoiding the trouble of moving various calibrating equipments from the vehicle to the field and then moving the calibrating equipments back to the vehicle after measurement, and bringing great convenience to the field calibration.

Description

technical field [0001] The invention relates to a combination of an on-site verification device for a power transformer with a voltage level of 220kV and below and a specially designed and refitted special vehicle, which meets the mobile operation for on-site verification of the transformer. Background technique [0002] So far, when conducting on-site calibration of power transformers, various calibration instruments and testing devices are consigned to the designated place for temporary installation. Therefore, it will take a lot of time and effort to set up the instruments before calibration. , and during the calibration, it is often necessary to shift the calibration equipment multiple times to meet the calibration of different groups of transformers. In this way, the installation, wiring and debugging must be repeated for each shift, which is not only time-consuming and laborious, but also more efficient. Low. In particular, the transformer calibration equipment of 110...

[0002] So far, when conducting on-site calibration of power transformers, various calibration instruments and testing devices are consigned to the designated place for temporary installation. Therefore, it will take a lot of time and effort to set up the instruments before calibration. , and during the calibration, it is often necessary to shift the calibration equipment multiple times to meet the calibration of different groups of transformers. In this way, the installation, wiring and debugging must be repeated for each shift, which is not only time-consuming and laborious, but also more efficient. Low

In particular, the transformer calibration equipment of 110kV and above cannot be moved by manpower and needs to be hoisted and followed, which makes on-site management difficult

Not only cause economic losses, but also affect the normal power supply guarantee
