Description
Technical field
The utility model relates to a kind of reactive power compensator, more particularly, is the reactive power compensator on a kind of 10KV bus.
Background technology
Reactive power compensator all is used on the remote transmission line usually at present, and then the reactive power of realization real-Time Compensation circuit, reduce line loss etc., and for the compensation of transformer station, we adopt outdoor framework type high-pressure reactive compensation device usually, this plant area area is bigger, and to realize that automatic switching is also cumbersome, need to adopt outdoor devices such as vacuum contactor, if local dust storm is bigger, protection to vacuum contactor just bothers very much so, the Installation and Debugging of this compensation way bother very much in addition, need carry out ground and pre-buried a lot of pipeline in advance, the secondary assembling is carried out at the scene again, also need transformer station itself that alternating current 220V power supply etc. is provided, sum up above-mentioned characteristics: floor space is big, it is high that components and parts self-protection grade is wanted, problems such as Installation and Debugging are loaded down with trivial details, under this geographical conditions in Xinjiang, just more seem thorny, itself is for Xinjiang, have vast territory, supply line is very long, natural conditions are more abominable, and a lot of 35kV transformer stations mostly are unattended stations, can reduce floor space and just seem that concerning whole investment economic worth is arranged very much in the process of building.
The utility model content
For solving the problem that prior art exists, the utility model proposes the reactive power compensator on a kind of 10KV bus, this device is installed simple, as long as just can install on the electric pole of 10KV outlet, whole floor space is little, and reliable.
The utility model can be achieved by the following technical programs:
Reactive power compensator on a kind of 10kV bus, comprise a control unit, a contact unit, a current limiting reactor capacitor unit, described current limiting reactor capacitor unit is connected with control unit by contact unit, also comprise a PT sampling unit, the one end is connected with 10KV bus input, and the other end links to each other with described control unit; Described control unit, contact unit, current limiting reactor capacitor unit, PT sampling unit place in the material shell.
As preferred embodiment of the present utility model:
PT sampling unit described in the utility model comprises sampling module and PT sampling work voltage module, this sampling module gathers electric current on the 10KV bus and voltage outputs to described control unit, and PT sampling work voltage module is connected to described control unit by a power module; Described PT sampling work voltage module output voltage is 220V; Described control unit comprises a central controller; Described control unit comprises a wireless communication module, and it is connected with described central controller; Described control unit also comprises fault alarm module and trip(ping) circuit module, and it is connected with described central controller respectively; Described central controller is provided with the man-machine interface of carrying out interactive dialogue with the people; Described control unit also places separately in the protecting sheathing.
By above technical scheme; the utility model is installed simple; only need on the electric pole of 10KV outlet, just can install; do not need additionally to plan and take transformer station's outdoor sports ground and do ground and preheating embedding line; and whole floor space is little; itself adopts the composite plate shell of high-protection level; can effectively protect inner components and parts to avoid the natural conditions of very severes such as Xinjiang; and it is reliable; need not transformer station simultaneously mains supply is provided, the controller sampling; action powers etc. all are to be supplied with by the secondary circuit of PT, and the secondary output rated voltage of PT is set at 220V; and this device can also be divided into a plurality of branch roads, the dynamic passive compensation that divides into groups.
