Configuration structure of 110KV double-bus PASS distribution device

Abstract

The invention discloses a configuration structure of an 110KV double-bus PASS distribution device. Two groups of bus devices respectively corresponding to a 1M bus and a 2M bus are arranged at intervals of bus devices; each bus device is respectively provided with one group of vertical fracture isolation switches, one ends of the vertical fracture isolation switches are connected with the corresponding buses, and the other ends of the vertical fracture isolation switches are connected with a lightning arrester and a transformer through flexible wires; one 145kV three-port PASSMO combined electrical appliance is respectively arranged at each interval of incoming wires and outgoing wires of a main transformer; a 145kV two-port PASSMO combined electrical appliance is arranged at each interval of bus couplings; and the 1M bus and the 2M bus adopt a support type tubular bus made of Al-Mg-Si alloy, the 1M sleeves of the PASSMO combined electrical appliances are connected with a 1M tubular bus through hard wires, and the 2M sleeves are connected with a 2M tubular bus through soft wires. The 110KV double-bus PASS distribution device has a simple structure, complete functions and is safe and reliable, the occupied area is small, and the extension, repair and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a configuration structure of a 110KV double-bus PASS power distribution device. Background technique [0002] Equipment selection is inseparable from the layout optimization of power distribution devices, the infrastructure investment of substations, and the safety and reliability of power grids. With the development of economy and the continuous increase of power demand, higher requirements are put forward for the quality and reliability of power supply. In order to standardize the construction of substations, shorten the power construction cycle, adopt advanced technology, high reliability, and maintenance-free electrical equipment, and reasonably control the project cost, it is an urgent requirement to improve the safe and reliable operation of the power grid and the efficiency of enterprises. [0003] Substation high-voltage switchgear is genera...

Problems solved by technology

[0006] If double busbars are used, the 110kV voltage level is higher, and the distance between the double busbars is controlled by the safety distance. Since the PASS M0 product is very compact in size, the horizontal distance between the bushing on the outlet side and the 1M bushing is only 2169mm. The difficulty in the design of the power distribution device lies in The use of conventional lead wires cannot meet the safety distance requirements, the accuracy of the PASS unit current transformer and the protection configuration need to meet the needs of metering and intelligence, and the maintenance of PASS combined electrical appliances, etc.
