CN202332577U - Earth protective device for current transformer - Google Patents

Abstract

The utility model discloses an earth protective device for a current transformer, relates to an electrical element and particularly belongs to an earth protective device for the current transformer. The current transformer consists of a casing (1) and a capacitor (2) arranged in the casing (1). The earth protective device is characterized in that pins (3) at two ends of the capacitor are respectively connected with a bolt (4); and epoxy resin (5) is poured on gaps among the capacitor, the pins at two ends of the capacitor, and the bolts connected with the pins and the casing so as to realize the sealing. According to the earth protective device disclosed by the utility model, the problem that the pins of the capacitor are easily broken off is solved and the capacitor can be connected with the outside through the bolts, so that the earth protective device has the beneficial effects of convenience in mounting and reliability in connection.

Description

The current transformer earth protective device

Technical field

The utility model relates to a kind of electric elements, particularly belongs to a kind of earth protective device of current transformer.

Background technology

Existing dry-type current transformer earth leakage protector comprises an electric capacity, and the electric capacity two ends respectively have a pin to be connected with external circuit; Because above-mentioned electric capacity pin is thinner; Be unfavorable for installing, and be prone to fracture phenomenon in installation process and after installing, cause protector to lose efficacy.

The utility model content

The purpose of the utility model promptly is to provide a kind of novel current transformer earth protective device, to reach the purpose of easy mounting and non-frangible.

The current transformer earth protective device that the utility model provided; Constitute by housing and built-in capacitor thereof; It is characterized in that; Capacitor two ends pin respectively connects a bolt, and casting epoxy resin is to realize sealing in the pin at above-mentioned capacitor, capacitor two ends and bolt that is connected with pin and the space between the housing.

The current transformer earth protective device that the utility model provided; Because capacitor is sealed in the epoxy resin; The problem of having avoided the capacitor pin to fracture easily, and capacitor can be connected with outside through bolt, so have and be convenient to installation, connect reliable good effect.
