Embodiment Construction

[0044] The specific implementation of the method for transforming a single-bus operating transformer station of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] See attached figure 1 , 2 , during transformation, move the load of No. 2 main transformer to No. 1 main transformer; disconnect the circuit breaker between No. The bus isolating switch corresponding to the section of the transformer, disconnect the incoming circuit breaker of the No. Double-bus related equipment, all tests are qualified; connect No. 2 main transformer equipment, connect No. 2 main transformer to No. The transformer interval equipment is energized; check the phases of the high and low voltage sides of the No. 2 main transformer and the No. 1 main transformer, and confirm that the phase is normal; move the load of the No. 1 main transformer to the No. 2 main transformer.

Abstract

The invention relates to the technical field of transformation of a high-voltage transformer substation, and discloses a transformation method of a single-bus operation transformer station. The transformation method comprises the following steps of moving a load of a second main transformer substation to a first main transformer substation, firstly carrying out segmentation on the second main transformer substation and then connecting into a double bus, and next, enabling the second main transformer substation to be powered on; next, carrying out power outage, access and power-on operations onthe first main transformer substation, and finally connecting the load; and carrying out processing on related equipment. According to the method, the original single-bus sectional operation is changed into double-bus operation, so that the operation of equipment is more flexible and reliable.

Description

technical field [0001] The invention relates to the technical field of transformation of high-voltage transformer substations, in particular to a method for transformation of single-busbar operation transformer stations. Background technique [0002] The work requirements of the high-voltage substation at the initial design stage, with the change of electricity demand, can no longer meet the current electricity demand. In addition, all equipment in the substation should be replaced regularly to eliminate potential safety hazards. [0003] The function of the high-voltage electric bus is to collect, distribute and transmit electric energy. Since the busbar is in operation, there is a huge amount of electric energy passing through it, and when it is short-circuited, it bears a lot of heat and electrodynamic effects. Therefore, the existing single-busbar substation is basically replaced by a double-busbar substation. The double-busbar power supply is reliable and the schedulin...
