Description

Capacitor convenient for judging overheating

Technical Field

The utility model relates to an electrical element field, concretely relates to condenser convenient to judge it is overheated.

Background

The capacitor is a device for holding electric charge, and the simplest parallel plate capacitor is formed by sandwiching an insulating dielectric between two metal electrodes, and when a voltage is applied between the two metal electrodes, electric charge is stored on the electrodes. Capacitors can be classified as metallized paper dielectric capacitors, ceramic capacitors, aluminum electrolytic capacitors, polystyrene capacitors, solid tantalum capacitors, glass glaze capacitors, metallized polyester capacitors, polypropylene capacitors, mica capacitors, and the like.

General condenser is owing to by the aluminum hull parcel, hardly judges inside whether take place overheated phenomenon, is unfavorable for the maintainer to judge, and if adopt accurate parts such as miniature temperature sensor, the cost will improve greatly, is unfavorable for economic benefits.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a be convenient for judge overheated condenser.

The purpose of the utility model is realized by adopting the following technical scheme:

the utility model provides a condenser convenient to judge overheated, includes aluminum hull, negative pole lead wire, anodal lead wire and condenser insulated core, and aluminum hull's bottom forms the recess, and the inner wall rigid coupling of recess has opaque fixed aluminum plate, and fixed aluminum plate's below is provided with the transparent glass board, and fixed aluminum plate's top thermosetting has the paraffin piece, and the drainage through-hole has been seted up to fixed aluminum plate's both sides simultaneously, and the paraffin piece is located between the drainage through-hole.

Preferably, the lower surface of the transparent glass plate is flush with the lower surface of the aluminum housing.

Preferably, the capacitor insulating core and the aluminum shell are fixedly connected through a plurality of supporting legs.

Preferably, the upper part of the aluminum shell is provided with a rubber sealing plug, and the positive lead and the negative lead penetrate through the aluminum shell and the rubber sealing plug and extend into the insulating core of the capacitor.

Preferably, the cross-section of the groove is circular.

Preferably, the positive lead and the negative lead penetrate through the aluminum shell and are sealed and fixed through glue.

Drawings

The present invention is further explained by using the drawings, but the embodiments in the drawings do not constitute any limitation to the present invention, and for those skilled in the art, other drawings can be obtained according to the following drawings without any inventive work.

Fig. 1 is a cross-sectional view of the present invention;

FIG. 2 is a structural view of a fixed aluminum plate, a transparent glass plate and a paraffin block.

Detailed Description

The invention will be further described with reference to the following examples.

Please refer to fig. 1-2, which illustrates a capacitor for conveniently determining overheating, including an aluminum casing 1, a negative lead 2, a positive lead 3, and a capacitor insulator core 4, wherein a groove 5 is formed at the bottom of the aluminum casing 1, an opaque fixed aluminum plate 6 is fixedly connected to the inner wall of the groove 5, a transparent glass plate 7 is disposed below the fixed aluminum plate 6, a thermal paraffin block 8 is fixed above the fixed aluminum plate 6, and meanwhile, drainage through holes 9 are formed at two sides of the fixed aluminum plate 6, and the paraffin block 8 is located between the drainage through holes 9. The lower surface of the transparent glass plate 7 is flush with the lower surface of the aluminum housing 1. The capacitor insulating core 4 is fixedly connected with the aluminum shell 1 through a plurality of support legs 10. The upper part of the aluminum shell 1 is provided with a rubber sealing plug 11, and the anode lead 3 and the cathode lead 2 penetrate through the aluminum shell 1 and the rubber sealing plug 11 and extend into the capacitor insulating core 4. The cross section of the groove 5 is circular. The positive lead 3 and the negative lead 2 are sealed and fixed by glue at the position of penetrating through the aluminum shell 1.

In addition, anodal lead wire 3 is connected with the inside anodal aluminium foil electricity of condenser insulation core 4, and negative lead wire 2 is connected with the inside negative pole aluminium foil electricity of condenser insulation core 4, and positive aluminium foil, negative pole aluminium foil isotructure inside condenser insulation core 4 belongs to the prior art category, the utility model discloses an invent point lies in the observation structure that fixed aluminum plate, clear glass board and paraffin piece constitute jointly, and the change of the inside structure of condenser insulation core 4 can not influence the utility model discloses an effect, the utility model discloses no longer detail the inside structure of condenser insulation core 4.

When the inside overheated that takes place of condenser, the heat passes through on the aluminium shell transmits the paraffin piece, when the temperature of paraffin piece exceeded melting temperature, flowed by the drainage through-hole after the paraffin piece melts to flow into the space between fixed aluminum plate and the transparent glass board, red pigment can be mixed into to the paraffin piece, in order to improve its visibility. Thus, when the capacitor is not overheated, the observer does not observe paraffin between the fixed aluminum plate and the transparent glass plate from the outside, and when the capacitor is overheated, the observer observes paraffin between the fixed aluminum plate and the transparent glass plate. The specific melting point of the paraffin wax can be selected from different paraffin wax types according to specific parameters of the capacitor. This condenser can the person of facilitating the use observe inside whether take place overheated to whether the decision needs to disassemble the condenser and overhauls or directly change, the cost is low moreover, and economic nature is good.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
