Abstract
The utility model discloses a vacuum arc quenching chamber solid-closure insulating sleeve of a vacuum ring net switch device, which belongs to the technical field of ring net distribution switch devices in an electric power system. The vacuum arc quenching chamber solid-closure insulating sleeve of the vacuum ring net switch device comprises a conductive rod, a voltage sensor and a vacuum arc quenching chamber, wherein the conductive rod and the voltage sensor are in an integrated structure which is formed by epoxy resin pouring. The vacuum arc quenching chamber is arranged on the right part of epoxy resin. According to the utility model, the voltage sensor, the vacuum arc quenching chamber and the insulating sleeve are organically combined together, and thus the vacuum arc quenching chamber solid-closure insulating sleeve has the performances of voltage detection and vacuum arc quenching, and has the advantages of compact structure and small volume.
Description
Technical field
The utility model belongs to looped network distribution switchgear technical field in the electric power system, is specially a kind of insulating sleeve with voltage sensor and vacuum interrupter.
Background technology
In urban power distribution network, because underground cable line has safety, reliably, advantage such as attractive in appearance, be that increasing distribution system adopts underground cable line, the distribution switchgear that underground cable line is commonly used is ring main unit and cable branch box, because ring main unit and cable branch box are mounted on the ground, its miniaturization becomes one of its key technology, in the market, ring main unit and cable branch box are for miniaturization, the switchgear of portion's installation within it adopts the SF6 switch mostly, and the SF6 switching gas is than CO2 serious greenhouse gases also, in case reveal, can cause environmental pollution, and common vacuum switchgear is too big owing to volume, the mode of connection of outlet is unfavorable for the connection of electric cable accessories.
Summary of the invention
The purpose of this utility model is for providing a kind of vacuum interrupter of vacuum looped network switch equipment to seal insulating sleeve admittedly in the underground cable power distribution network of city, realizing miniaturization, intellectuality and the environmental protectionization of switchgear.
The technical scheme that realizes above-mentioned purpose is: the vacuum interrupter of vacuum looped network switch equipment seals insulating sleeve admittedly, it is characterized in that: comprise conducting rod, voltage sensor and vacuum interrupter, voltage sensor and conducting rod are the integral structures that adopts poured with epoxy resin to form, and the right part of epoxy resin is provided with vacuum interrupter.
The material of described conducting rod is red copper.
Described voltage sensor is capacitive divided voltage sensor.
The utility model organically combines voltage sensor, vacuum interrupter and insulating sleeve, not only has voltage detecting, vacuum extinction performance, also has compact conformation, the advantage that volume is less.
The signal that the utility model adopts capacitance type potential transformer to detect is weak electric signal, is convenient to digital translation and communication requirement based on the IEC61850 technology.
