Problems solved by technology

[0002] As shown in the accompanying drawings of this manual figure 1 As shown, the explosion-proof performance of the traditional power capacitor 1 is to achieve the explosion-proof effect by installing a single explosion-proof plate 12 inside the capacitor, that is to say, the explosion-proof performance of the entire product depends on this one explosion-proof plate 12, if this explosion-proof plate 12 If it fails, the entire product will fail

Embodiment 1

[0034] Such as figure 2 As shown, in the housing 10 of the power capacitor 1, a lower positioning sleeve 2 and an upper positioning sleeve 3 are set, and the two ends of the core group 4 are respectively covered by the lower positioning sleeve 2 and the upper positioning sleeve 3. fixed.

[0035] The core group 4 is fixed by a special upper and lower positioning sleeve technology. First, put each independent unit 5 that has been produced into the lower positioning sleeve 2 according to the requirements of the design documents and process documents, and then assemble the positioning sleeve 3, so that each independent unit 5 is firmly fixed in the horizontal direction Living.

[0036] The adoption of the above technical solution ensures the stability of the core group 4 in the vertical direction, and the core group 4 is firmly fixed in the horizontal and vertical directions. During production and processing, the installation is convenient, the positioning is accurate, the co...

Embodiment 2

[0038] Such as Figure 2 to Figure 6 As shown, the core group 4 of the present invention is respectively fixed by the lower positioning sleeve 2 and the upper positioning sleeve 3: the lower positioning sleeve 2 and the upper positioning sleeve 3 are all provided with the independent The shape of the end of the unit 5 is a corresponding concave cavity, the independent unit 5 is inserted into the concave cavity, and the side of the independent unit 5 forms an elastic tight fit with the concave cavity.

[0039] The lower positioning sleeve 2 and the upper positioning sleeve 3 are located on the same plane, and are provided with a plurality of concave cavities for installation. The plug-in structure is adopted to insert the independent unit 5, and each independent unit 5 is inserted through a tight fit with certain elasticity. The unit 5 is fixed, the position is accurate, it is not easy to loosen, and the installation is also very convenient.

Embodiment 3

[0041] The number of independent units 5 in the power capacitor 1 according to the present invention is equal to or more than three.

[0042] Each independent unit 5 of the present invention has anti-explosion mechanism, and the products of different specifications adopt the independent unit 5 that quantity is not equal, but have 3 independent units 5 at least.

Abstract

The invention discloses a multiple blast-resistance structure of a power capacitor, which comprises a plurality of discrete units (5), and each of discrete units (5) is equipped with a blast-resistance mechanism. By adopting the technical scheme, the invention controls the blast-resistance structure by use of a plurality of control points; and if one control point fails, other control points can still play a role of blast-resistance, thereby avoiding the defect that the traditional product just has one or two blast resistance mechanisms, and greatly improving the safety and the reliability of the product when in use.

Description

technical field [0001] The invention belongs to the technical field of power switch cabinets, and relates to a low-voltage compensation capacitor for an AC system. More specifically, the invention relates to a multiple explosion-proof structure of a power capacitor. Background technique [0002] As shown in the accompanying drawings of this manual figure 1 As shown, the explosion-proof performance of the traditional power capacitor 1 is to achieve the explosion-proof effect by installing a single explosion-proof plate 12 inside the capacitor, that is to say, the explosion-proof performance of the entire product depends on this one explosion-proof plate 12, if this explosion-proof plate 12 If it fails, the entire product will fail. Contents of the invention [0003] The problem to be solved by the present invention is to provide a multiple explosion-proof structure of the power capacitor, and the purpose is to make the explosion-proof performance of the power capacitor mor...
