6The on-load switch of (sulphur hexafluoride), the circuit breaker of installing in it is positioned at one and is filled with SF
6In the arc control device of gas, this SF
6Gas is a kind of nontoxic inert gas, and as a kind of dielectric, it is used widely in various electric equipments, but SF
6Gas can resolve into the very high material of toxicity under the high temperature of electric arc, this material has very strong toxicity to human body, simultaneously SF
6Gas still is a kind of greenhouse gas, and its influence to greenhouse effect is CO
2More than 20,000 times of gas.In actual applications, fill SF
6The equipment of gas all exists the problem of gas leakage, the accident of might blasting, also might damage human body, more can strengthen greenhouse effect, also can strengthen the work of maintenance personnel amount.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be easy to use and the novel loop-network switch cabinet of Environmental Safety.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of novel loop-network switch cabinet, comprise on-load switch, spring operating mechanism, bus row, fuse and casing, on-load switch is packed in the side in the casing, front end at casing is provided with the control panel that shows each equipment working state in it, it is characterized in that: the on-load switch that connects on described every phase circuit is the solid-state insulation load switch that the one cast is made, comprise vacuum breaker module in it, isolating switch module and earthed switch module, isolating switch module and earthed switch module one end are by high-voltage connection terminal connection bus row, the other end ground connection of earthed switch module, the other end of isolating switch module connects an end of vacuum breaker module, the other end of vacuum breaker module connects the high-pressure side of transformer by a fuse, at two montants that drive vacuum breaker module and isolating switch module break-make respectively of on-load switch upper end slip setting-in, the upper end of these two montants connects the output toggle arm of spring operating mechanism.
And a lightning arrester that is inlaid on the casing is connected in parallel between described isolating switch module and the vacuum breaker module.
Advantage of the present utility model and beneficial effect are:
The utility model is simple in structure, be easy to use, the solid-state insulation load switch that employing is made by vacuum breaker module, isolating switch module and the cast of earthed switch module one, because circuit breaker adopts the vacuum chamber arc extinguishing, the problem that gas leakage can not occur, also can not cause the injury of human body, can long-living greenhouse effect, guaranteeing and improving under the prerequisite of product electric property, realized zero discharge, can be safely, operation reliably.
