Abstract
The utility model relates to a double safety overvoltage absorber which is composed of a box body, a capacitor, a resistor, a lightning arrester, etc. The utility model is characterized in that the capacitor is arranged in the box body, one end of the capacitor is connected with one end of the lightning arrester by a conducting wire, the other end of the capacitor is connected with one end of the resistor by a conducting wire, the other end of the resistor is connected with one end of a connecting plate which is fixedly connected to screw bolts passing through a resistor lead, and one end of the connecting plate is connected with the other end of the lightning arrester which is fixed on screw bolts. The utility model can effectively absorb overvoltages, and protect loading equipment from being damaged by a high current, and has the advantages of light weight, small size, and environmental pollution avoidance.
Description
The utility model relates to a kind of dual fail-safe surge absorber, relates to a kind of overvoltage protection that is applicable on the electric power system 3-35KV equipment specifically, belongs to overvoltage protection.
At present; on overvoltage protection, use piezo-resistance, zinc oxide arrester etc. mostly; but these devices can not absorb overvoltage effectively, reduce superpotential wave head steepness; existing structure can not make big electric current shunting; can not effectively protect load equipment not to be subjected to the infringement of big electric current; explosive; thereby influence the normal operation of power system device; simultaneously; owing in superpotential protection, use oil immersion and few oily device; so its volume is big, heavy, and easily produces oil leakage phenomenon, even cause the harm of burning and to the pollution of environment.
The purpose of this utility model just is: design a kind of dry type surge absorber that is formed in parallel by HYW lightning arrester and RC, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that it is mainly by casing (1), electric capacity (2), resistance (3), lightning arrester parts such as (4) are formed, it is characterized in that being equipped with in the casing (1) electric capacity (2), one end of electric capacity (2) is connected with an end of lightning arrester (4) by lead (5), and be fixed on the bolt (15), the other end of electric capacity (2) is connected with an end of resistance (3) by lead (5), the other end of resistance (3) is connected with a end of connecting plate (16) on being fixed in bolt (15) by resistance lead (14), and the other end of connecting plate (16) is connected with the other end of lightning arrester (4) on being fixed on bolt (15).
Its feature is that also casing (1) is made up of box bottom (7), box side (8) and box cover (9), is provided with charges (10) around the interior electric capacity of casing (1) (2).
Its feature is that also electric capacity (2) can and be connected into electric capacity (2) by lead (5) by a plurality of electric capacity, is provided with dividing plate (6) between a plurality of electric capacity.
Its feature is that also resistance (3) is wound on the skeleton (13), the bottom of skeleton (13) is provided with sealing plate (12), the side is provided with porcelain overcoat (11) around the skeleton (13), and cap seal plate (17) is serially connected on the bolt (15), and is fixed on the box cover (9) by bolt (15).
Compared with prior art it can absorb overvoltage, reduce superpotential wave head steepness the utility model effectively; can make big electric current shunting; can effectively protect load equipment not to be subjected to the infringement of big electric current; this absorber is because of being dry type; so it is in light weight, volume is little, and has avoided the harm of leakage of oil, burning; having avoided the pollution of environment, is a kind of novel overvoltage protection.
