Abstract

The invention discloses a lightning arrester. The lightning arrester comprises a ceramic sleeve and an inner sleeve, wherein the inner sleeve is mounted in the ceramic sleeve; the inner sleeve comprises an upper sleeve, middle part sleeves and a lower sleeve; the upper sleeve, the middle part sleeves and the lower sleeve are connected end to end in a sleeving manner from the top to bottom in sequence; the upper sleeve is provided with an upper end cover; the lower sleeve is provided with a lower end cover; the lower part of the upper end cover is connected with a coil; the lower end of the coil is connected with a zinc oxide piezoresistor sheet; the lower end of the zinc oxide piezoresistor sheet is connected with the lower end cover; the upper sleeve and each middle part sleeve are provided with one coil separately, and the coils are connected in series; the number of the middle part sleeves is three; the exterior of the ceramic sleeve is convex to form an umbrella shape; and the zinc oxide piezoresistor sheet is arranged in the lower sleeve. Generally, the lightning arrester has the advantages of simple structure, reasonable design, easy installation and maintenance and good use effect.

Description

technical field [0001] The invention belongs to the field of electric equipment and relates to a lightning arrester. Background technique [0002] Surge arresters are used to protect electrical equipment from high transient overvoltage hazards, limit the freewheeling time, and often limit the freewheeling assignment of an electrical appliance. This term includes any external clearance necessary for the proper function of the appliance in the operational installation, whether or not it is an integral part. The lightning arrester currently used has a complex structure and is inconvenient to use and install. Contents of the invention [0003] The object of the present invention is to provide a lightning arrester, which adopts a socket design, has a simple structure, is easy to manufacture and install, has good use effect and has extremely high use value. [0004] The object of the present invention is achieved in this way: a lightning arrester includes a ceramic bushing and...
