Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0053] Such as figure 1 As shown, the present invention provides a novel rail transit power distribution system auxiliary debugging method, the method comprising:

[0054] In step S1, rail transit uses rails and the earth as the main return path. During normal operation, a large load current flows through the grounded distribution network. When a short-circuit ground fault occurs in the traction network or lightning current passes through the grounded distribution network, it may cause the conductor of the grounded distribution network to break due to heat or high-current electric power. The defect of the grounded distribution network will threaten the operation safety and personal safety of the power supply system. Therefore, it is necessary to focus on auxiliary debugging of the grounded distribution network.

[0055] In step S2, the power ...

Abstract

The invention relates to a power distribution system auxiliary-commissioning-testing method of novel rail transit. The method includes: carrying out auxiliary commissioning testing on a grounded powerdistribution network, and judging whether the same is normal; carrying out auxiliary commissioning testing on a power transformer, and judging running status thereof; and carrying out auxiliary commissioning testing on voltage transformation equipment, and judging running status thereof. Three novel auxiliary-commissioning-testing methods are designed in the method to respectively carry out auxiliary commissioning testing on the grounded power distribution network, the power transformer and the transformer equipment in a power supply system; and on the basis of the above method, comprehensiveand effective commissioning testing can be carried out on important power equipment in a power distribution system, and safety and reliability are improved.

Description

technical field [0001] The invention relates to the field of power distribution systems of new rail transit, in particular to an auxiliary debugging method for the power distribution system of new rail traffic. Background technique [0002] In recent years, rail transit has developed rapidly, bringing great convenience to our travel. The power distribution system is a power network system composed of a variety of power distribution equipment and power distribution facilities that transforms voltage and directly distributes power to rail transit. In order to ensure the safe and efficient operation of rail transit, it is necessary to carry out auxiliary debugging on the power distribution system of rail transit. [0003] In the auxiliary commissioning of the traditional power distribution system, the maintenance and analysis of transformers, cables, circuit breakers, and equipment power loads in the power distribution system mainly rely on the manual analysis of power workers...
