Abstract
The utility model relates to a centralization control protective cabinet for a large capacity capacitor, overcoming the difficulty of the separate installation of the existing protective equipment and building fixed mounts. The centralization control protective cabinet for a large capacity capacitor comprises all protective equipment such as a reactor, a discharge coil, a lightning arrester and an isolating switch as an entity, and the protective equipment are respectively and fixedly contained and connected electromechanically in a metallic cabinet. The cabinet is provided with external porcelain wall bushing binding posts to form independent and complete set of equipment. When the centralization control protective cabinet for a large capacity capacitor is utilized, the centralization control protective cabinet is needed to be arranged near a capacitor, power source inlet wires are connected with corresponding porcelain wall bushing binding posts, the binding posts of the capacitor correspond to the other set of porcelain wall bushing binding posts, and thus protective action for the capacitor can be formed.
Description
The present invention relates to the corollary apparatus of large value capacitor, be specially adapted to the supporting protection equipment of large value capacitor.
Large value capacitor is the power factor that is used for improving 50HZ or 60HZ AC electric power systems, reduces line loss, improves the energy-saving equipment of supply power voltage quality.In use need to be equipped with reactor, discharge coil, lightning arrester and isolating switch control and protection equipment as capacitor.The above-mentioned supporting protection equipment of existing installation need be built fixing installing rack, and each equipment is installed in respectively near the capacitor.The capacitor as shown in Figure 1 and the installation diagram of corollary equipment, installing rack 9 is formed fixing and mounting bracket by concrete column and several transverse bar of three settings, the 1st, capacitor, its corollary equipment reactor 2, discharge coil 3, lightning arrester 4, isolating switch 5, power cable 6 then is separately fixed at the different parts of installing rack.Such layout and installation form, floor space is big, and the capital construction work amount is big, and consumptive material is many, user's inconvenience, unsafe factor is also high.
The object of the present invention is to provide a safety, the collection control protection cabinet of the large value capacitor that capital construction is simple, floor space is little.
Technical scheme is as follows; with isolating switch; discharge coil; lightning arrester and reactor are contained, are fixed in the metal cabinet respectively; and according to its operation principle with between each equipment organically electricity join; be provided with insulator binding post through walls cashier's office in a shop at metal, can be electrically connected with electrical network and capacitor respectively, constitute the complete set of equipments of an independent completion---collection control protection cabinet.During use; only need collect control protect cabinet be installed in capacitor near; and with the high pressure inlet wire; the binding post of capacitor respectively with the binding post of collection control protection cabinet mutually electricity connect; just can play control and protective effect to capacitor; the large value capacitor collection control protection cabinet as shown in Figure 2 and the installation diagram of capacitor; wherein 1 is capacitor; 14 are collection control protection cabinet; the high pressure inlet wire is introduced in the collection control protection cabinet by insulator binding post 8 through walls; again by insulator binding post 9 through walls; totally six of 10() with the six roots of sensation binding post of capacitor mutually electricity connect; formation is to the collection control protective effect of capacitor; having avoided building the work of fixing and mounting bracket, simplified installation procedure and reduced installation cost, is to substitute existing capacitor corollary equipment ideal equipment in bulk.
Embodiment is described in further detail this utility model below in conjunction with parallel three phase large value capacitor collection control protection cabinet.
Fig. 3 and Fig. 4 are the internal structure schematic diagram of large value capacitor collection control protection cabinet.
Reactor 2, discharge coil 3, lightning arrester 4, isolating switch 5 is contained respectively to be fixed in the metal cabinet 11, for the ease of making transportation, the metal cabinet can be by two-layer composition up and down, reactor 2 is fixed on the bottom of metal cabinet lower floor, discharge coil 3 be fixed on metal cashier's office in a shop the layer the bottom, lightning arrester 4 by fixed mount 12 be fixed on metal cashier's office in a shop the layer sidewall on, isolating switch 5 is by fixed mount 13 tilting being fixed in the metal cabinet of upper strata, and isolating switch is by operating handle 15 controls that are located at metal cabinet outside.During installation; double layer of metal cabinet stack up and down; and fix with securing member; the centre has insulator 6 through walls to make two-layer communicating up and down; constitute a complete collection control protection cabinet; being provided with insulator binding post 8.1,8.2,8.3 through walls at the top of cabinet can join with three groups of high pressure inlet wires, and rear wall is provided with insulator binding post 9.1,9.2,9.3,10.1,10.2,10.3 through walls and can be respectively joins with the six roots of sensation binding post of capacitor.Electrical connection such as Fig. 3 of its inside show, one end of isolating switch and insulator binding post 8(8.1 through walls, 8.2,8.3) fix electricity and connect, the other end of isolating switch respectively with lightning arrester 4, discharge coil 3 end and insulator binding post 9(9.1 through walls once, 9.2,9.3) fixedly electricity connect, discharge coil 3 other end once then with insulator binding post 10(10.1 through walls, 10.2,10.3) fixedly electricity connect, one end of reactor 2 is by insulator 6(6.1 through walls, 6.2,6.3) and insulator binding post 10(10.1 through walls, 10.2,10.3) fixedly electricity connect, the other end of reactor is mutual short circuit then.Its catenation principle figure as shown in Figure 5, power line at first passes through isolating switch, more respectively with lightning arrester, capacitor connects, reactor is serially connected in the capacitor back, discharge coil is in parallel with capacitor.
In addition for the indication network voltage condition, the operating state of monitoring discharge coil is drawn light current by the two ends of discharge coil secondary, connects indicator light respectively, voltmeter and small transformers, and the secondary coil of each transformer serial connection back communicates with the two ends of a zero phase-sequence relay.Indicator light voltmeter and zero phase-sequence relay are located at the appearance of protection cabinet, so that observe.For making protection each equipment in the cabinet be convenient to maintenance, but the one side of metal cabinet can be made into the valve arrangement of start or stop.
