Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] Such as figure 1 , figure 2 and image 3 The schematic diagram of the circuit used in the whole set of test methods for automatic switchover shown in common is used in the mutual investment circuit module. The mutual investment circuit module includes a first analog transformer PT1 and a second analog transformer PT2. The first analog transformer PT1 is connected to the first analog bus on the high voltage si...

Abstract

The invention discloses a standby power source automatic put-in switching full group test complete test method and a device thereof. The method comprises three test steps of: independently running section I and section II buses to test, running the section I and section II buses in parallel to test, and running the section I and section II buses in parallel to test. In the invention, various passive contact signals required for the test of a standby power source automatic put-in device can be generated, the device has simple structure and is convenient to operate, the working efficiency of the test can be improved, and the test of various functions can be completed. The defects of inaccurate testing, item missing, difficult matching and the like existing in the traditional auxiliary device are overcome, and the manual locking function and the joint switching function of the standby power source automatic put-in device can be tested conveniently. The test device has the advantages of small size, low cost and good interference resistance and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of substation technical verification, in particular to a whole set of test method and test device suitable for standby automatic switchover. Background technique [0002] The main function of the standby automatic switch is to automatically and quickly put the backup power supply or equipment into operation after the working power supply or equipment of the substation is disconnected due to failure or other reasons, so as to ensure that the substation does not lose power supply and provides reliable power supply to users. [0003] At present, in the inspection work of relay protection, in order to ensure the reliability and correctness of the action logic and circuit of the backup power automatic switching device, it is necessary to connect the backup power automatic switching device with the secondary control circuit for testing. They are all carried out by using auxiliary devices such as simulated circuit ...
