Abstract
Provided is an indoor 35 kV bushing, comprising a bushing main body of an epoxy resin sleeve with an umbrella skirt at the exterior, wherein a conducting bar penetrates through the bushing main body, a coil is built-in the bushing main body, a connecting terminal is arranged on the surface of the bushing main body and the coil is connected with the connecting terminal with a connecting lead. According to the utility model, the indoor 35 kV bushing has reasonable structure, the coil is built-in to obtain the electrical signal for providing the error-prevented performance, the indoor 35 kV bushing can be grounded for shielding, and has the advantages of small local discharge capacity, big creepage distance and good anti-fouling performance.
Description
Technical field
The utility model relates to a kind of bushing of 35kV electric pressure, is a kind ofly to be used for high-voltaghe compartment to become switch cubicle equipment mainly be the bushing of supports insulative and electric action.
Background technology:
The former design electric field of bushing that uses in high-tension apparatus at present is more concentrated, and is inhomogeneous because of the electric field pole that physical dimension caused between bus-bar room epoxy bushing and the metallic plate, do not have anti-error performance, and there is discharge the part under operating voltage, and electric property is relatively poor.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and provides a kind of rational in infrastructure, has anti-error performance, can improve the electric field issue, reduces the indoor 35kV bushing of partial discharge.
The technical scheme that technical problem adopted that solves is: a kind of indoor 35kV bushing, comprise that appearance is provided with the casing main body of the epoxy resin cover of full skirt, casing main body is penetrated with conducting rod, it is characterized in that at casing main body built-in sensitive circle, be provided with binding post on the casing main body surface, induction coil is connected with binding post with connecting lead.The built-in sensitive circle obtains the signal of telecommunication and is connected with external display by binding post, with realization signal is detected and controls, and has increased anti-error performance.The built-in sensitive circle also can connect by binding post, can be used as shielding action, improves Electric Field Distribution, reduces partial discharge.
Induction has enclosed the effect of transducer, and when induction coil specifically used, casing main body was provided with mounting disc, and the mounting disc end face is provided with a circle seal groove, and binding post is located in the mounting disc.Place the sealing ring of phase establishing in the seal groove of mounting disc, can be installed on the case lid of transformer, seal.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, in establish induction coil, can obtain the signal of telecommunication, anti-error performance is provided; Advantages such as also but ground connection connects as shielding action, and it is little to have a partial discharge quantity, and creepage distance is big, and soil resistance is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model example structure schematic diagram;
Among the figure 1, conducting rod 2, seal groove 3, binding post 4, induction coil 5, casing main body 6, mounting disc
Embodiment:
As shown in Figure 1, a kind of indoor 35kV bushing comprises that appearance is provided with the casing main body 5 of the epoxy resin cover of full skirt, and casing main body 5 is penetrated with conducting rod 1, and blasting treatment is carried out on conducting rod 1 surface, the combining closely of reinforced epoxy and conducting rod surface; Casing main body 5 is provided with mounting disc 6, and mounting disc 6 end faces are provided with a circle seal groove 2, and mounting disc 6 is provided with two binding posts 3, and binding post 3 is the M4 inserts.Casing main body 5 built-in sensitive circles 4, induction coil 4 usefulness connect lead and are connected with binding post 3.Distance between induction coil 4 and the conducting rod 1 is more than the 30mm, and to satisfy induction coil 4 insulation thicknesses, creepage distance can reach 25mm/kV.Built-in sensitive circle 4 obtains the signal of telecommunication and is connected with external display by binding post, with realization signal is detected and controls, and has increased anti-error performance.Built-in sensitive circle 4 also can connect by binding post, can be used as shielding action, improves Electric Field Distribution, reduces partial discharge.2 li sealing rings of placing the phase establishing of the seal groove of mounting disc 6 can be installed on the case lid of transformer, seal.
Claims (2)
1. indoor 35kV bushing, comprise that appearance is provided with the casing main body of the epoxy resin cover of full skirt, casing main body is penetrated with conducting rod, it is characterized in that at casing main body built-in sensitive circle, be provided with binding post on the casing main body surface, induction coil is connected with binding post with connecting lead.
2. a kind of indoor 35kV bushing according to claim 1 is characterized in that above-mentioned casing main body is provided with mounting disc, and the mounting disc end face is provided with a circle seal groove, and binding post is located in the mounting disc.
