Embodiment
Due in the operation of transformer station, at synchronization, it is no matter the low-pressure side of same transformer or in same transformer station, low voltage parallel capacitor group and high and low pressure shunt reactor can not drop into simultaneously.Generally, the transformer substation construction initial stage due to duty ratio comparatively light, the charge power of 500kV is relatively large, often drops into shunt reactor in this stage.Along with transformer station's load increases, transformer reactive loss increases gradually, and shunt reactor exits, and the number of units that capacitor drops into increases gradually.
In each interval of main transformer low-pressure side reactive power compensator, partial separation is transform as the special interval not only capacitor can installed but also reactor can be installed.Drop into shunt reactor at the first stage of construction of transformer station, and along with the increase of substation's on-load, need reactor to be changed to capacitor according to operation.If this capacity reactance exchanges interval and can realize dismounting exchange capacity reactance equipment easily and fast and can meet service requirement, the reactive power compensator then often organizing main transformer once can be gone up together at first stage of construction, thus effectively can save the occupation of land scale of transformer station and invest accordingly, better economic benefit can be obtained.
Consider construction scale be often organize the transformer station that main transformer configures 3 groups of electric capacity and 2 groups of reactance, do not need 5 intervals of once go up needed for neat capacitor and reactor, but arrange 4 power distribution equipments power up perhaps reactance occupation of land interval.Wherein, capacitor is only installed in 2 intervals, and reactor is only installed in 1 interval, and 1 interval can be installed capacitor and also can be installed reactor, and equipment detachably exchanges.Three groups of electric capacity or two groups of reactance can be run at most as required under every platform main transformer.
For realizing the exchange of above-mentioned Capacitor banks and Reactor banks, needing basis, fence and earth mat for the two to make improvements, the present invention is based on this and propose a kind of uniform based.
As shown in Figure 1, the present invention includes fence 100 and be arranged on and realize uniform based, post insulator Quick Connect Kit and the support Quick Connect Kit that Capacitor banks and Reactor banks carry out at Same Site exchanging in fence, three jointly forms and exchanges basis.Capacitor installation fence is of a size of 5m × 12m, and reactor fence is of a size of 5m × 10m, and in equipment interchange process, fence 100 should adopt unified specification, and therefore, fence 100 size as selection gist, should should adopt 5m × 12m specification using comparatively large equipment size.
Wherein, as shown in Figure 1 and Figure 2, uniform based refers to the mixed base simultaneously comprising Capacitor banks basis 2 and Reactor banks basis 1.Because this mixed base is larger, and there is different sedimentations, cause basis easily to split, therefore need in mixed base, arrange arrangement of reinforcement 3; Simultaneously due to the existence of reactor, require can not there is thick hardware in antimagnetic distance, and the reinforcing bar or other metals formation that form closed circuit in basis, can not be had, so arrangement of reinforcement 3 of the present invention is made up of grounding lead wiring and fiberglass, fiberglass is nonmagnetic substance, and there is higher intensity, original reinforcing bar can be avoided to generate heat and to cause the generation of basic crack situation, improve the mechanical property of mixed base preferably; And this mixed base all are buried Tie Tong and are crossed inc grounding lead wiring and be connected with main grounding grid 4.
As shown in Figure 3, Figure 4, post insulator Quick Connect Kit comprises and is arranged on plant bottom case 5 and post insulator reserves the U-shaped steel plate 7 buried between iron 6, the sealing baffle 11 that this U-shaped steel plate 7 comprises upper strata flange steel plate 9, lower floor's flange steel plate 10 and is positioned at therebetween; Its at the middle and upper levels flange steel plate 9 be connected with plant bottom case 5 by bolt 8, lower floor's flange steel plate 10 and post insulator be reserved to be buried iron 6 and welds.Like this, when removing bolt 8, the post insulator on top can be removed, conveniently realize Fast Installation and dismounting.In addition, for the purpose of firmly, between upper strata flange steel plate 9 and lower floor's flange steel plate 10, be also provided with stiffener 13, stiffener 13 is vertically arranged relative to sealing baffle 11.
As shown in Figure 5, Figure 6, the installing hole 16 that support Quick Connect Kit comprises housing apparatus support 14 and the steel plate 18 be positioned at bottom equipment supporter, bury between iron 15 at steel plate 18 and support and flange component 17 is set, above-mentioned flange component 17 also can be U-shaped steel plate, and flange component 17 top is connected with steel plate 18 by construction bolt 19, buries iron 15 bottom flange component 17 with support and weld, like this, remove construction bolt 19, Fast Installation and the dismounting of equipment supporter 14 can be realized.In addition, floor 22 is set in flange component 17, to strengthen its fastness.Cover plate 20 can also be set between equipment supporter 14 and installing hole 16.
