Abstract
The utility model discloses a reactive compensation system for a high-voltage ring main unit. The reactive compensation system comprises a wire connecting bar-TMY, wherein a connecting wire is led out from the wire connecting bar-TMY, and is connected in series with a knife switch-QSA and a current mutual inductor-BH sequentially and then is divided into two parallel branches; one of the two parallel branches is connected with a lightening arrester-FYS and is connected to the ground; and the other parallel branch is connected with a fuse-RT, an alternating current contactor-CJ, an overload relay-JR and a reactive compensation controller-NWKL. According to the reactive compensation system, the structure is simple, the volume is small and the cost is low, and power supply parameters, performance and power supply safety can be improved. The reactive compensation system can be widely used in power distribution substations and box-type transformer substations of load centers such as urban residence communities, high-rise buildings, large-scale public buildings, factories and enterprises, etc.
Description
Technical field
The utility model relates to high pressure ring cabinet field, is specifically related to a kind of reactive compensation system of high pressure ring cabinet.
Background technology
The high pressure ring cabinet is for improving power supply reliability, make the user obtain power supply from both direction, usually power supply network being connected into annular.This supply power mode abbreviates ring network power supply as.Exchange in the 10KV distribution system at industrial and mining enterprises, residential quarters, harbour and skyscraper etc., because of load is held not quite, on-load switch or vacuum contactor control are adopted in its high tension loop usually, and are furnished with the high-tension fuse protection.This system adopts ring network power supply usually, use on the high-tension switch cabinet general custom and be called ring main unit.Ring main unit is except to the power supply of this distribution substation; Its high voltage bus also will be through the through current (promptly through the electric current of this distribution substation bus to the power supply of adjacent distribution substation) of annular electric supply net; Therefore the high voltage bus cross section of ring main unit will be selected in looped network through current sum according to the load current of this distribution substation, to guarantee not running overload of high voltage bus in service.
The reactive power compensation system is in an indispensable very important position in power supply system, reasonably select compensation arrangement, can accomplish to reduce to greatest extent the loss of network, and power grid quality is improved.Otherwise,, possibly cause electric power system, voltage fluctuation, many factors such as harmonic wave increase as selecting or improper use.
The utility model content
The purpose of the utility model provides a kind of reactive compensation system of high pressure ring cabinet, to improve power supplying efficiency, improves the power supply environment.
The technical scheme of the utility model is following:
A kind of reactive compensation system of high pressure ring cabinet; Include line bank TMY; It is characterized in that: draw wiring from described line bank TMY; And be divided into two parallel branches after being connected in series knife switch QSA summation current transformer BH successively, and be connected with lightning arrester FYS and ground connection in one of them parallel branch, be connected to fuse RT, A.C. contactor CJ, overload relay JR and idle compensating control NWKL in another parallel branch successively.
The reactive compensation system of described high pressure ring cabinet is characterized in that: bus row is adopted in described wiring.
The beneficial effect of the utility model:
The utility model system configuration is simple; Has the advantage that volume is little, cost is low, can improve power supply parameter and performance and power supply safety; Improved power supplying efficiency; Improved the power supply environment, extensively applied in the power distribution station and box-type substation of load centers such as Urban House sub-district, skyscraper, large public building, factory and enterprise.
