Description
Technical field
The utility model belongs to high pressure detection technique field, and in particular to a kind of new totally-enclosed disc insulators of GIS.
Background technology
GIS (Gas Insulated Switchgear, gas-insulated enclosed switch) disc insulator is to be used to connect GIS
Insulated support between 2 air chambers.Mainly there are three kinds at present：Disc insulator without shielded layer, the totally-enclosed basin with shielded layer
The disc insulator of formula insulator, Strip casting hole shielded layer.Superfrequency detection method for local discharge is the detection of GIS state of insulations
Key technology means, this method mainly carry out superfrequency partial discharge by external extra-high video sensor or built-in extra-high video sensor
Signal acquisition.It is exhausted that external extra-high video sensor is mainly used for the disc insulator without shielded layer, the benzvalene form of plug hole shielded layer
Edge；Built-in extra-high video sensor is mainly used for the totally-enclosed disc insulator with shielded layer.
Built-in extra-high video sensor collection signal needs GIS device producer to be reserved on tank body and mouth is fixedly mounted, which has
Shortcomings：First, it is difficult to ensure that GIS insulating safety distances, easily trigger the insulation defects such as floating potential；Second, the later stage can not
Change monitoring position, detection efficiency are low；Third, directly affect the air-tightness of tank body, globality and the workload for increasing perforate.
External extra-high video sensor collection signal, though without reserved installing port, when being detected using plug hole, by sensor
It is placed in outside the plug hole of the disc insulator of Strip casting hole shielded layer, there are internal signal decay greatly, and easily by external interference etc.
Shortcoming；For the disc insulator without shielded layer, though detection signal is good, there are the outside electromagnetic radiation of GIS itself is big, detection
The shortcomings of signal is easily by external interference.
The content of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art, there is provided a kind of new totally-enclosed benzvalene form insulation of GIS
Son.
The utility model includes the totally enclosed insulating basin body of insulating materials, and the outside diameter of insulating basin body is more than GIS
Safe distance.
The metal screen layer of circular ring shape be coated on insulating basin body along wall outer surface, be provided with cast on metal screen layer
Hole, plug hole extend radially through metal screen layer；Metal screen layer inner wall corresponds to cast hole site and is provided with antenna slot, plug hole to
Interior opening is in the range of antenna slot slot bottom；It is embedded in the cambered surface plate aerial and cambered surface insulating trip of antenna slot slot bottom form fit
In antenna slot, wherein cambered surface plate aerial and insulating basin body is affixed along wall, cambered surface insulating trip and cambered surface plate aerial
Cambered surface is bonded, and is insulated between cambered surface plate aerial and metal screen layer by cambered surface insulating trip.
The side wall of the plug hole is step-like, metal cover board is provided with the top of plug hole, metal cover board is arranged on
On step, it is fixedly connected by screw with metal screen layer；Signal output connector mounting hole is provided with metal cover board.
The utility model uses integral structure, and the extra-high video sensor (i.e. antenna stack) of annular is built into insulating basin
It is interior, do not change the electrical safety distance and insulation performance of GIS, you can reach the detection result of built-in sensors.The design shields
Superior performance, good in anti-interference performance, avoids the problem of needing perforate built in GIS sensors, it also avoid easily drawing built in sensor
Send out the insulation defects such as suspended discharge.Annular UHF antenna, detects bandwidth, signal receiving plane is big, can efficiently catch built in outfit
Catch Partial discharge signal in GIS.
