Abstract

The invention discloses a large current generating device for bushing test and its use method, and relates to the technical field of power equipment testing. The system includes a test end device and a control end device. , iron core, current transformer and bushing under test, the control terminal equipment includes computer console, control cabinet, switch cabinet and temperature control box, computer console and control cabinet control signal connection, control cabinet and switch cabinet control signal connection, switch The cabinet controls the switch and voltage regulation of the feedthrough transformer through the contact voltage regulator, the current transformer outputs current for the internal circuit of the control cabinet, and the temperature control box collects the temperature signal of the tested bushing through the thermocouple and transmits it to the control cabinet. The invention has the advantages of high equipment integration, simple device use, short wiring time, and is suitable for high-current tests of various bushings.

Description

technical field [0001] The invention relates to the technical field of power equipment testing, in particular to a large current generating device for bushing testing and a method for using the same. Background technique [0002] The bushing needs to carry out a high-current test in the factory and fault diagnosis test to check whether the bushing can meet the high-current operation requirements and whether the temperature rise of each component is normal. This test is usually completed by a high-current generating device. The transformer generates a large current, and the bushing needs to be connected to the secondary main circuit of the large current generating device, and then auxiliary connected to the current transformer, temperature sensor and compensation device, etc., to complete the measurement of various parameters and current compensation functions. Conventional devices of this type have the following problems: First, the integration of equipment is not high, and ...
