Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of 110kV with earth leakage detection functions and above cross interconnected protective earthing case.
The purpose of this utility model is realized by following proposal:
A kind of 110kV and the cross interconnected protective earthing case of above band detection of electrical leakage type, comprise casing, insulating base I, the copper connecting rod I running through insulating base I inside, insulating base II, the copper connecting rod II running through insulating base II inside, protector and connection copper bar, described insulating base I and insulating base II are fixed in casing, and the bottom of insulating base I and insulating base II extends casing outside, one end that insulating base I and insulating base II stretch out casing is respectively arranged with binding post; Described protector is in series with protector leakage detector, described insulating base I, copper connecting rod I, protector, protector leakage detector, connect copper bar, insulating base II and copper connecting rod II three-phase cross interconnected.
Described casing is stainless steel casing.
Described insulating base I and insulating base II all adopt full skirt to design.
Binding post and the cable sheath of described insulating base I are connected and fixed, the binding post ground connection of described insulating base II.
The utility model protector leakage detector has earth leakage detection functions.During installation, engineering site only need be fixed casing, and cable strips out copper core and presses binding post on insulating base I, then is screwed with copper connecting rod I, finally wraps waterproof in junction; The direct ground connection of binding post of insulating base II, thus the connection realizing " external cabling terminal-protector-protector leakage detector-earth terminal ", just can show current electric leakage state after protector leakage detector installation and operation.
The beneficial effects of the utility model:
The whole casing of the utility model is hermetically sealed, improves reliability; Casing external cabling, without the need to again opening during installation, simple, convenient, fast; Box house connects rationally arrangement, and casing is inside and outside adopts insulating base, plays and insulate and inside and outside connection function with casing; Insulating base adopts full skirt design, increases creepage distance, prevents casing charged simultaneously, improves reliability, is convenient to hotline maintenance;
The utility model adds protector leakage detector; on-line monitoring can be carried out to the running status of protector; by the electrical leakage observing protector leakage detector, hotline maintenance personnel judge whether protector damages, convenient maintenance, improves the security of operation of whole electrical network simultaneously.
