Abstract
The utility model discloses a rain-proof waterproof terminal box, including arranging the sealed pad on the terminal box body threading mouth terminal surface in, place flange on the sealed pad, install current transformer on the flange, install the shrouding on the rear opening of terminal box body, be connected with cable joint on the terminal box body, the utility model is used for deposit the cable conductor to connect gas-insulated metal-enclosed switchgear and current transformer, adopt this structure, can prevent effectively inside the rainwater infiltration switchgear, avoid taking place the incident, improve insulating level.
Description
Technical Field
The utility model relates to a current transformer terminal box for gas insulated metal enclosed switchgear is a rain-proof waterproof terminal box particularly.
Background
In the gas insulated metal-enclosed switchgear that runs for many years outdoors, the current transformer terminal box exposes in the air for a long time, and cable joint can take place ageing deformation, and in addition, the glass who scribbles at sealed edge during the assembly is glued and is also ageing easily, comes to arouse temporarily in rainy season to cause the rainwater to get into in the terminal box along the cable, leads to switchgear to damage because of insulating badly.
Disclosure of Invention
An object of the utility model is to the not enough of existence among the above-mentioned prior art, provide a rain-proof waterproof terminal box for gas insulated metal enclosed switchgear current transformer, this terminal box easily processes, simple to operate, safe and reliable.
The utility model adopts the technical proposal that:
a rainproof and waterproof junction box comprises a sealing gasket arranged on the end face of a threading opening of a junction box body, a connecting flange is arranged on the sealing gasket, a current transformer is installed on the connecting flange, a sealing plate is installed on a rear opening of the junction box body, and a cable connector is connected onto the junction box body.
Furthermore, a square opening is arranged at the rear of the junction box body, a circle of flanging is arranged at the square opening, and a circular hole is arranged at the front of the square opening; the end face of the junction box body connected with the current transformer is arranged to be an inclined plane.
The connecting flange is characterized in that two end faces of the connecting flange are respectively provided with a sealing groove, and O-shaped sealing rings are respectively arranged in the sealing grooves of the two end faces of the connecting flange.
Furthermore, a sealing strip is arranged between the sealing plate and the junction box body.
The utility model has the main advantages that: rain-proof waterproof, simple structure, easily processing, simple to operate. The sealing gasket is arranged on the end face of the threading port of the junction box, the connecting flange is arranged, the O-shaped sealing rings are arranged in the sealing grooves on the two end faces of the connecting flange, and then the current transformer is installed and is firmly connected by bolts. A sealing gasket and a sealing plate are arranged on a square opening of the junction box and then are connected with the metal-enclosed switchgear, so that the openings of the junction box can be effectively waterproof and rainproof after the switchgear is arranged.
