Problems solved by technology

Since the transformation of the rural power grid, the outer insulation layer of the down-conductor of the meter box often has the phenomenon of aging. When it rains, the rainwater will seep into the wire from the cracked insulation layer, and the rainwater that penetrates into the wire will flow backward along the wire into the meter box. switch, causing power outages for users, and sometimes endangering personal safety

Abstract

The invention discloses a water-proof device for incoming line of meter box, including a barrel. Two rings are set at interval in the middle section of the barrel. Drainage holes connected with inner cavity of the barrel are set between two rings. The drainage holes are connected with diversion tubes. Front-end caps are installed in front of the barrel. Both the barrel's front-end part and front-end cap are equipped with threads used for connection. The barrel rear-end part is provided with rear-end cap. Both the barrel's rear-end part and rear-end cap are equipped with threads used for connection. Both the front-end cap and rear-end cap are equipped with holes for wires. The invention can be installed on the downlead in front of the meter box switch. The invention can prevent rainwater from entering to reduce failure outage of users and ensure power supply safety.

Description

technical field [0001] The invention relates to a waterproof device for meter box inlets. Background technique [0002] With the rapid development of power system construction and the continuous improvement of users' requirements for power supply reliability, higher requirements are put forward for the stability and safety of power supply. Since the transformation of the rural power grid, the outer insulation layer of the down-conductor of the meter box often has the phenomenon of aging. When it rains, the rainwater will seep into the wire from the cracked insulation layer, and the rainwater that penetrates into the wire will flow backward along the wire into the meter box. switch, causing power outages for users, and sometimes endangering personal safety. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a meter box inlet waterproof device, which is used to prevent rainwater from pouring backward through the...
