On-site calibration equipment of integrated electric power voltage transformer

Abstract

The invention discloses on-site calibration equipment of an integrated electric power voltage transformer. The equipment comprises: a standard voltage transformer, an intermediate connection cylinder, a high voltage bushing, a booster test transformer, a first flange, a left flange, an upper flange, a right flange and a second flange. The first flange is arranged on the standard voltage transformer. The left flange is arranged on an interface of a left side of the intermediate connection cylinder. The right flange is arranged on the interface of a right side of the intermediate connection cylinder. The second flange is arranged on the booster test transformer. The upper flange is arranged on an upper part of the intermediate connection cylinder. The first flange is connected with the left flange. The second flange is connected with the right flange. The high voltage bushing is connected with the upper flange. In a scheme of the invention, the standard voltage transformer and the booster test transformer are combined as one body. Quantities of the high voltage bushings can be reduced, equipment wiring can be simplified and a integrated level of the equipment can be increased. Simultaneously, a vehicle requirement of on-site calibration mechanization and automation operation of the 330KV electric power voltage transformer can be satisfied.

Description

technical field [0001] The invention relates to an integrated on-site calibration device for power voltage transformers, which can meet high-voltage metering work such as on-site calibration of power voltage transformers, and belongs to the technical field of high-voltage metering equipment. Background technique [0002] So far, there is no integrated equipment that can meet the calibration of various types of voltage transformers such as capacitive voltage transformers, electromagnetic voltage transformers, and GIS internal voltage transformers with a voltage level of 330kV. At present, the on-site verification of voltage transformers is still a test operation on the temporary assembly and wiring of calibration equipment such as scattered standard voltage transformers and booster equipment. During the test, it is necessary to frequently adjust the capacity and inductance of the reactor and to repeatedly hoist, assemble, and adjust to meet the requirements of on-site calibra...

AI Technical Summary

Problems solved by technology

When calibrating different groups of transformers on site, it is necessary to move the calibrating equipment multiple times, each time relocating requires repeated installation, wiring, and debugging, which is time-consuming, laborious, and inefficient, which not only causes economic losses, but also affects normal operation. Power supply guarantee; and the equipment is large in size, heavy in weight, low in automation and complex in operation, and cannot be centrally installed in the power transformer on-site calibration vehicle with mechanical automation operation capability of the transformer on-site calibration solution
