Description

A kind of integration module capacitor

Technical field

The utility model relates to a kind of reactive power compensation low voltage parallel capacitor.

Background technology

The shunt capacitor that tradition is used for reactive power compensation is the low pressure self-healing type parallel condenser, and interior filling medium mostly is mineral oil, microwax or quartz sand; Being used for the low-voltage complete reactive power compensator also needs join the electrical equipment such as circuit breaker, fling-cut switch, fuse outward, connects loaded down with trivial detailsly, and failure rate is high, keeps in repair consuming time; And mostly be with electric appliances and install concentratedly, easily misfortune and neighbours when breaking down.

The utility model content

The problem that the utility model exists in order to solve above-mentioned capacitor, and a kind of integration module capacitor that a kind of wiring is simple and convenient, maintenance saves time and interchangeability is good is provided.

In order to achieve the above object, the technical solution adopted in the utility model is as follows:

A kind of integration module capacitor, described capacitor comprises:

One metal shell;

One face shield, described face shield is installed in the metal shell front end, is provided with main electrical scheme hole and control terminals rim of the mouth on it;

One low pressure self-healing type parallel condenser, described low pressure self-healing type parallel condenser is placed in the metal shell;

One air circuit, described air circuit is placed on the face shield;

One intelligent compound switch plate, described intelligent compound switch plate is placed on the face shield, and connects the low pressure self-healing type parallel condenser;

One control circuit board, described control circuit board is placed on the face shield, and connects the intelligent compound switch plate.

In preferred embodiment of the present utility model, described main electrical scheme hole is opened in the top of face shield, and described control terminals rim of the mouth is opened in the lower-left end of face shield.

The utility model not only has integrated and modularization, also has simultaneously overload, short circuit, overcurrent protection and operating passing zero function, greatly improves the safety and reliability of product, and the failure rate that reduces product.

In addition, the utility model wiring is simple and convenient, and maintenance saves time, and interchangeability is good, thereby has solved the structural deficiency of the complete reactive power compensator of conventional low.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model internal structure schematic diagram;

Fig. 2 is the utility model front view.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1 and 2, a kind of integration module capacitor of the utility model comprises metal shell 1, main electrical scheme hole 2, face shield 3, circuit breaker 4, intelligent compound switch plate 5, control circuit board 6 and low pressure healing formula shunt capacitor 7.

Metal shell 1 is for the protection of internal components, the internally charged element of isolation and prevent outside other elements of internal fault impact.

Face shield 3 is plastic face mask, and it is placed in the front end of metal shell 1, as front end sealing and guidance panel, can be used for installing and fixing circuit breaker 4 and control circuit board 6 etc.

Circuit breaker 4 is the small air circuit breaker, and it is placed on the face shield 3, is mainly used in internal circuit is done isolation, overcurrent, short-circuit protection.
