Portable spare power automatic switching calibrator

Abstract

The invention relates to the technical field of substation equipment detection, disclosing a portable spare power automatic switching calibrator. The portable spare power automatic switching calibrator is provided with a transmission and distribution circuit of a primary system pipe network of an analog substation, and comprises two analog high-voltage bus circuits, two analog low-voltage user circuits and a power supply, wherein the contacts of a high-voltage DL (delay line) module connected with the two analog high-voltage bus circuits are connected with a direct-current power supply respectively by a vacuum switch; the high-voltage DL module is connected with the analog low-voltage user circuits by a low-voltage DL module and a vacuum switch; and a low-voltage sectioned DL module is arranged between two analog low-voltage user circuits. The portable spare power automatic switching calibrator provided by the invention can accurately and reliably detect the function of a spare power automatic switching automatic device, is convenient in use and low in maintenance and manufacture cost, and ensures that power failure accident hidden danger brought by practical belt switch driving is avoided and the power supply reliability is enhanced, thereby providing convenient conditions for detecting the spare power automatic switching device and having strong economical benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of transformer substation equipment inspection, and is especially suitable for a portable backup automatic switching calibrator for testing the logic function of a power backup automatic switching device when primary equipment is not powered off. Background technique [0002] With the application of new technologies, social life is increasingly dependent on power supply, and the reliability of power system power supply has become an important indicator to measure power quality. In order to improve the reliability of power supply, the power supply mode of dual power supply is often used as backup for each other. The importance of automatic switching device for backup power supply can be seen. However, for a long time, how to conveniently, reliably and efficiently test the reliability of the automatic switching device has become a difficult problem in the secondary equipment calibration of the power system.

Problems solved by technology

However, for a long time, how to conveniently, reliably and efficiently test the reliability of the automatic switching device has become a difficult problem in the secondary equipment calibration of the power system.

Because there are many parameters in the acquisition system when the standby automatic switching device is working, the action involves a wide range of circuit breakers, and the actual risk of transmission experiments with switches is high.

At present, the general calibrator and the simulated circuit breaker are independent devices, and the wiring is complicated when doing the test of the self-injection device, and the human factors are greatly affected during the test, and the test results are unreliable.
