Problems solved by technology

[0002] The existing collective and bulk power capacitors have the following disadvantages: maintenance and repair are difficult, and the collective product needs to be terminated and put into operation if it fails, and the whole set must be returned to the factory for repair, which involves a lot of manpower and material resources and affects the use of users; The damaged product can be replaced on the spot, but it also brings a lot of inconvenience to the user due to its complex assembly and many joints. The internal heat is large, and the medium is easy to cause aging and affect the service life of the product; the chance of overlapping weak points on the film of the existing power capacitor is relatively large, which reduces the service life of the product

Embodiment Construction

[0015] The structure of the building block power capacitor of the present invention is as follows Figure 1-Figure 4 As shown, it includes 3 or more building block power capacitor modules 1. A plurality of building block power capacitor modules 1 are assembled by bolt connection and assembly to form a capacitor bank, and the building block power capacitor module 1 and the post insulator 2 are connected by bolts , The building block type power capacitor module 1 is provided with a bushing 8, and the electrical connection between the building block type power capacitor modules 1 and between the capacitor banks is realized through the bus bar 3. The entire capacitor bank is located on the foundation base 4, which can realize rapid installation on site, and facilitate on-site expansion according to the capacity requirements of the compensation device. Specifically, each building block power capacitor module 1 has four connection mounting holes on the top and bottom, and multiple bu...

Abstract

The invention discloses a cordwood power capacitor, comprising three and more than three cordwood power capacitor modules; the cordwood power capacitor modules are connected and assembled by a bolt to form a capacitor bank; the cordwood power capacitor modules are in bolted connection with post insulators; sleeve tubes are arranged on the cordwood power capacitor modules; the sleeve tubes are wire inlet and outlet terminals of the cordwood power capacitor modules; and the cordwood power capacitor modules and the capacitor bank realize electrical connection through a bus bar. The cordwood power capacitor has the advantages of simplicity in installation and maintenance, low noise, convenience in capacity extension and renovation as well as long service life.

Description

Technical field [0001] The invention belongs to the technical field of capacitor equipment and relates to a building block type power capacitor. Background technique [0002] The existing collective and bulk power capacitors have the following shortcomings: maintenance and repair are more difficult, the assembly product must be terminated and put into operation if it fails, the entire unit must be returned to the factory for repair, a lot of manpower and material resources are invested and users are affected; The damaged product can be replaced on the spot, but due to its complicated assembly and a large number of joints, it also brings a lot of inconvenience to the user; the capacity between the capacitors is fixed, which is not convenient for the user to expand and modify the capacity. In order to adjust the compensation, the entire device is sometimes replaced; the core The internal heat generation is large, and the medium is likely to cause aging to affect the service life of...
