Description

A kind of Partial Discharge Detection sonac detects box
Technical field
This utility model relates to a kind of Partial Discharge Detection sonac and detects box.
Background technology
Closed gas insulation in combined electric appliance is chopper, disconnecting switch, earthed switch, current transformer, mutual induction of voltage Device, spark gap, bus and outlet casing tube etc. are combined, and high-voltage charged body is sealed in full SF6 gas-insulated medium Canister in, it has good insulating properties, is widely used in high voltage power transmisson system.GIS is almost all of to be cut-off, Measuring and excess voltage preventer is all sealed in pressure vessel, device interior is the most subjected to the atmosphere, and use SF6 gas medium insulating properties and arc extinction performance are excellent, and therefore GIS has that reliable height, maintenance work be little, the time between overhauls(TBO) The feature such as longer.Although but GIS operational reliability is the highest, and the GIS overall operation feelings that in-site installation puts into operation Condition is good, but owing to GIS is totally enclosed combined electric appliance equipment, once has accident to occur, can be than general separate type The equipment of opening wide causes even more serious consequence, and breakdown maintenance will be extremely complex, and repair time is long, and repair process is up to two More than week.
GIS have an accident the many main cause of comparison be certain burr occurs in the mill, install in parts occur loosening, internal Dirt or inside have what numerous reasons such as defect caused to have metal impurities, insulator surface to occur.When these problems occur, Under environment under high pressure, device interior often shows as shelf depreciation, discharges in various degree and for a long time under conditions of existing, and it is potential Defect result in shelf depreciation and constantly occur, apparatus insulated performance also and then will progressively deteriorate and expand, and ultimately result in whole Apparatus insulated environment is breakdown, so will largely threaten the safe operation of GIS, thus causes equipment fault and have a power failure, Bring about great losses.Along with the application in power system of the switchgears such as GIS is more and more extensive, its safe and stable operation pair Stablizing of safeguards system is most important.Partial Discharge Detection is to grasp GIS internal operation situation, finds that potential insulation lacks in time The effective method of one fallen into, also by Partial Discharge Detection can be classified to internal flaw and identify, contributes to existing Accident GIS is analyzed by field.
For GIS partial discharge detection method many employings superfrequency and ultrasonic Detection Method, have developed multiple GIS both at home and abroad On-the-spot Partial Discharge Detection equipment, presently used detection device Host build is relatively big, detection sensor by signal transmssion line with Main frame is connected, the detection of superfrequency to be carried out when GIS device carries out live detection, ultrasonic signal to be carried out Detection, in order to machine operation is judged more accurately.Superfrequency detection is different with ultrasound detection principle, uses not The position being positioned on GIS in same detection sensor, and detection also differs.The layout of each area GIS is different, Need to face during detection and climb, sensor is stretched to the various operations such as distant place.Invention is had to propose at present a kind of portable Multi-functional Partial Discharge Detection detection bar, fixes partial discharge detecting sensor in GIS detects, and this detection bar is by can Telescopic insulating bar, sensor fastening device, amplifier fixed bin etc. form, and both can install sonac and also can install extra-high Frequently, it is achieved a bar is dual-purpose.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of Partial Discharge Detection ultrasonic sensing Device detection box, this detects box bottom box body equipped with flexible member, it is possible to achieve give ultrasonic sensor one during detection External thrust, makes sensor probe be fitted tightly on detected housing, is greatly improved the accurate of ultrasound wave Partial Discharge Detection Property and capacity of resisting disturbance, improve Partial Discharge Detection convenience.
For achieving the above object, this utility model employing following technical proposals:
A kind of Partial Discharge Detection ultrasonic sensor detects box, and including detection box body, described detection box body inner bottom part is fixed In order to support the flexible member of sensor, described detection box body is rotationally connected with detection box support.Office is carried out using detection bar With detection box body mounting ultrasonic sensor during portion's discharge signal detection, flexible member is set ultrasonic sensor can be made to be close to GIS housing, improves accuracy in detection;Detection box body and detection box support are rotationally connected simultaneously, and box body can rotate fortune between support Dynamic, to need to adjust angle according to actually detected position.
Described detection box body lateral wall is equipped with rotary connector, and rotary connector is connected with detection box support;Detection box body is along rotation Turn connector be in detection box support between rotate to adjust angle.
Preferably, described rotary connector number is two, and two rotary connectors are detecting box body lateral wall relative on position Arrange;Rotary connector at two symmetric positions is set, detection box body can be made relatively reliable with the connection of support.
Described detection box support includes that the body of rod being connected with rotary connector, the described body of rod are connected with supporting plate.
Preferably, it is connected between described supporting plate and the body of rod and has trapezoidal plate;The size making supporting plate reduces, convenient operation detection The end of box support, more increases the support force of detection box support while saving material.
Preferably, described supporting plate is installed with gear;Can be attached with detection bar by gear, utilize detection bar to enter Row detection work, improves operation flexibility.
Preferably, described detection box side wall is provided with signal transmssion line groove;For protecting holding wire and ultrasonic sensor At wiring.
The beneficial effects of the utility model are:
1. this utility model detection box uses simple, conveniently.
2. this utility model detection box can be effectively improved detection equipment convenience.
3. ultrasonic sensor can be fitted tightly over GIS housing by this utility model detection box, improves accuracy in detection, it is to avoid The detection error that manual operation brings.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of this utility model detection box;
Fig. 2 is the schematic front view of this utility model detection box body;
