Description

Bar following formula reactive power compensator

The utility model relates to the circuit arrangement or the system of power supply or distribution, particularly applies to the bar following formula reactive power compensator that electric power system 10/0.4KV electrical network carries out reactive power compensation.

Though at present reactive power compensator widespread in transformer station, the power distribution room of enterprise, but the reactive loss of having ignored the following electrical network of electric power system 10/0.4KV, and in power supply network, the loss electric weight of transformer accounts for the 20-25% of the total losses amount of whole power supply, detect factually, the pole transformer power factor of city of Hangzhou is about 0.7, suburbs and counties under the jurisdiction of a large city are generally about 0.65, the transformer of a 315KVAR can only provide the active power of (0.7-0.65) * 315==220-205KW in other words, utilance is 70-65%, if power factor is increased to 0.95, a then same transformer can provide the active power of 70-95KW more.

The tool statistics, at present the area, Hangzhou has surplus the outdoor pole transformer 2000, Zhejiang Province has an appointment 10,000, the whole nation has ten thousand of 15-20 approximately, is facing energy shortage, today that supply of electric power day is becoming tight, if can adopt " bar following formula " reactive power compensator, to relaxing the power shortage situation, improve the utilance of electrical network and controller switching equipment, very significant beyond doubt.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of open-air bar following formula reactive power compensator that outdoor pole transformer is carried out reactive power compensation that is applicable to is provided.

The purpose of this utility model can be achieved through the following technical solutions: bar following formula reactive power compensator comprises and has door, the casing of blind window, and casing is connected with anchor ear by channel-section steel.

The utility model can also come further perfect by following scheme: keeper is equipped with at the back side at casing, and top cover has oblique gesture, in casing and the door thermal insulation board is housed, and base and top cover have ventilation hole, can also be provided with side door on the casing.

The effect of anchor ear is that device is fixed on the electric pole, keeper can prevent that locking apparatus rotates on electric pole, top cover has oblique gesture can prevent ponding, and the base of device and top cover have ventilation hole can make up and down convection current and can prevent ponding in the casing of air, is provided with side door so that maintenance.

Below by embodiment and contrast accompanying drawing the utility model is described in detail.

Fig. 5 is the left view of the utility model embodiment.

Fig. 6 is the right view of the utility model embodiment.

Fig. 7 is the schematic perspective view of the utility model embodiment.

As shown in the figure, bar following formula reactive power compensator is the cabinet type body structure that a high-quality cold-rolled steel sheet bending forms, external coating is with anti-corrosion, device can be divided into top cover 6, casing 2 and base 11 3 parts are formed, between with the fixing (see figure 1) of connecting bolt 3, connect two circular anchor ears 13 at the back side of casing 2 upper-lower position respectively by channel-section steel 14, anchor ear 13 is by the fixing (see figure 2) of bolt and electric pole 12, keeper 19 plays the role of positioning, anti-locking apparatus rotates (see figure 4) around electric pole, keeper can be two bars, be welded on box back surface as two angle bar, also can be divided into several sections with weight reduction, the upper design of top cover 6 becomes the inclined-plane (see figure 5), can prevent ponding, the inwall of casing and door 10, thermal insulation board 18 all is equipped with in 17 inboard, the material of thermal insulation board can be an asbestos board, cystosepiment etc., the bottom of top cover 6 forms edge 6-1 greater than casing 2 (see figure 3)s, 6-2,6-3, have rectangular ventilation hole 15 on it, base 11 is the pentahedron of a four sides bending downwards, also have rectangular ventilation hole 15 (see figure 3)s on it, to form cross-ventilation up and down, help ventilation and heat, be provided with side door (17) (see figure 5) in the left side of casing, about dividing, the box house components and parts isolate setting and left surface and front opening structure for two, position, inner space and machine volume have effectively been reduced, open offside door 17 and can intuitively arrive isolating switch 20, controller 21, fuse 22, open 10 at main entrance and can see that box house is equipped with two guide rails 7, be fixed with air switch 5 on the guide rail, A.C. contactor 8, capacitor 9 is equipped with in the bottom, the handle 1 that is contained in the casing outside uses when installing, blind window 4 on the casing also has been the ventilation and heat effect, and the hole, garden 16 on the base 11 is an entrance hole.23 is earth stud, is connected with ground wire.

The utility model is applied to harsh environmental conditions on the outdoor bar, and volume is little, and be convenient to install, observe, keep in repair, the well-ventilated, anti-ponding is antirust.
