Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] In the description of the present invention, the backup power automatic input device is referred to as standby automatic input device or standby automatic input device. There are several switch cabinets in the urban rail transit substation, and each switch cabinet is equipped with a P143 protection device. The P143 protection device integrates the transformer The functions required for the relay protection of the power station, including detecting whether the...

The invention discloses a method for testing a backup power automatic input device. The debugging of the backup power automatic input device includes a standby automatic input test and a protection action blocking standby automatic input test; during the test, relay protection is used The device simulates whether there is pressure or no pressure on the section I busbar and section II busbar, and detects whether the bus tie circuit breaker is automatically switched on under the condition of self-contained switching; at the same time, it also detects that the bus tie circuit breaker meets the protection action In the case of blocking automatic switching, whether automatic switching is blocked. The test method of the present invention only needs to ensure the correct setting of the state sequence in the relay protection device, and automatic operation can be realized through fault triggering; it has the characteristics of high test accuracy, high success rate, and strong reliability, and the automatic switching test can be completed in one step; Moreover, the method of the invention requires few testers, and the overall debugging efficiency of the substation is greatly improved when the debugging work is busy.
Description
technical field [0001] The invention relates to the field of power supply and distribution, in particular to a method for testing a backup power automatic input device. Background technique [0002] The backup power automatic switch-in device is referred to as standby self-switching. In the prior art, the standby automatic switch-on test is generally performed by using a voltage simulation device to simulate two incoming line voltages, and the loss of incoming line voltage is achieved by the experimenter unplugging one simulated incoming line power supply. accomplish. Since the incoming line is three-phase AC, manual operation may cause the three test lines to be pulled out one after the other longer than the delay setting time of the standby automatic switching, so that the starting condition of the standby automatic switching cannot be triggered. In the protective action blocking standby self-switching test, it must be ensured that the incoming line protection device dete...
