Abstract
The utility model discloses an indoor compact capacitor device comprising a capacitor bank, and a series reactor and a current transformer connected with the capacitor bank; each phase of the capacitor bank is arranged in a lateral position in two rows and is arranged on a metal framework; three phase frameworks are stacked to form a capacitor tower; antifouling pillar insulators are arranged between every two layers; the series reactor is a dry type iron core series reactor; the compact capacitor device can greatly reduce arrangement field under a prerequisite of reliable technology and reasonable economic performance, is very suitable for an indoor transformer station application place, and complies with a basic policy of saving land in our nation and a guidance ideology of resource saving, environmental friendly, and industrialization.
Description
Technical field
The utility model relates to a kind of capacitor device, specifically relates to a kind of indoor capacitor device that is applied in.
Background technology
The capacitor device of station use indoors is the outdoor capacitors device.The capacitor group three-phase of this capacitor device keeps flat, and adopts the hollow string anti-, and its floor space is big, and leakage field is big, and very inapplicable indoor transformer station uses.
Summary of the invention
The purpose of this utility model provides a kind of indoor compact capacitor device little, magnetic leakage free that takes up room.
For achieving the above object, the utility model is by the following technical solutions:
A kind of indoor compact capacitor device, it comprises capacitor group and the series reactor summation current transformer that is connected with the capacitor group, described capacitor group is every to be the double arrangement of lying on one's side of one deck mutually, be installed on the metal framework, three plate hanger closed assemblies constitute a capacitor pylon, per two interlayers dirty t shore insulator of setting up defences; Described series reactor is the dry-type iron-core series reactor.
Described earthed switch and lightning arrester are installed on the same support.
Adopt the utility model of technique scheme, have the following advantages:
A) by the structural design of three-phase closed assembly, realized that the densification of capacitor device arranges that the fence size only is 4m * 6.1m, more conventional capacitor device is saved more than 50%, and it is remarkable to optimize effect.
B) the dry-type iron-core string resists to have does not have characteristics oily, that volume is little, leakage field is weak: 1. compare with the oil immersed type reactor, it does not have oily characteristic can avoid considering fire protection requirement; 2. compare with dry type half heart or dry type magnetic screen reactor, the dry-type iron-core reactance can be made the three-phase product, and volume is little, installation is simple, is conducive to the realization of compact capacitor device; 3. compare with dry-type air-core reactor, its expose magnetic field a little less than, can avoid the electromagnetic interference to secondary device, avoid the heating of ferromagnetic material around the equipment simultaneously.
C) at the characteristics of the indoor layout of compact frame type capacitive apparatus; carried out design optimization in problems such as wiring and protected mode, components and parts selections on the basis of continuity conventional ripening scheme; under the prerequisite of the technical performance of assurance device, further improved engineering adaptability.
D) the cell capaciator cost occupies most proportions in the device overall cost, and compact frame type capacitive apparatus does not increase construction investment.
In sum, this compact capacitor device is reliable in the assurance technology, under the prerequisite of economical rationality, significantly reduce to arrange the place, be particularly suitable for indoor transformer station application scenario, meet fundamental state policy that China " saves the area " and the guiding theory of " amphitypy one is changed ".
