Description
[
technical field]
The utility model relates to the technical field of electrical control, and particularly electric power system is for the technical field of distribution.
[
background technology]
High pressure complete set of equipments (high voltage power distributing cabinet) refer to voltage 3kV and more than, the indoor and outdoor AC switchgear run in frequency 50Hz and following electric power system.Be mainly used in the control and protection of electric power system (comprising the users such as power plant, transformer station, electric line and industrial and mining enterprises); both can need a part of power equipment or circuit input or out of service according to operation of power networks; also when power equipment or line failure, faulty component can be excised fast from electrical network, thus ensure the safety of the normal operation of no failure part in electrical network and equipment, operating maintenance personnel.
Present stage, high voltage power distributing cabinet model was based on metal armouring power distribution cabinets such as KYN28A, HXGN, its main circuit is 10KV AC system, and the electric operation power in power plant and transformer station adopts now is all DC power supply, so in first stage distribution system, the generally outer configuration of neck one or several direct current cabinets in power plant and transformer station, direct current supply is carried out to the manipulation of controller switching equipment, this supply power mode can meet the power supply requirement of control loop substantially, but wherein also there are some indeterminable problems.
First: direct current cabinet volume is large, generally can reach the size (600*800*2200) of a station power distribution equipment, have requirement to the space of electric substation.Secondly, direct current cabinet needs cable to connect, and which increases the failure rate (needing to safeguard etc. cable) of electric substation.Again, the increase of direct current cabinet also adds the manufacturing cost in power transmission and distribution system, installation cost etc. greatly.Finally, the maintenance of direct current cabinet, as crossed the setting increasing direct current cabinet, then needs the regular discharge and recharge to direct current cabinet and battery to safeguard separately, increases maintenance cost.
Present stage conventional electrical distribution industry basic scheme:
1. incoming line cabinet+metering cabinet+powered cabinet+change cabinet+PT cabinet used+feed out cabinet
2. incoming line cabinet+metering cabinet+powered cabinet+PT cabinet+feed out cabinet+direct current cabinet distribution system
And the self-powered integrated form high voltage power distributing cabinet after improving only needs self-contained electric system to be integrated in power distribution cabinet, then can cancel change cabinet used and direct current cabinet distribution system, concrete scheme is: the self-powered integrated form incoming line cabinet+metering cabinet+powered cabinet of self-powered integrated form+PT cabinet+feed out cabinet (only needing wherein two cabinets to use self-powered integrated form power distribution cabinet just can meet the demand of electric power system to DC control supply).
