Description
Technical field
The utility model relates to a kind of dielectric voltage withstand pick-up unit of electric power tool, particularly a kind of insulating tool vertical hanging device.
Background technology
The insulation safety instrument is the indispensable managing security tools and instruments of transformer station or other high-voltage electrical apparatus place, and is good for guaranteeing insulation safety instrument insulating property, guarantees user of service's safety, must regularly carry out withstand voltage test to detect its insulating property to it every year.Insulation rod and electroscope are indispensable customary insulation security tools in the insulation safety instrument, and its routine test workload is maximum.
When trial voltage can satisfy whole test condition of insulation safety instrument, the insulation safety instrument generally adopted vertical hanging, and an end is fixed on the high-field electrode, and other end ground connection is carried out test.At present, adopt the vertical hanging mode to carry out insulation rod and electroscope test, not enough below main the existence:
1, the vertical hanging high-field electrode is the pressure point of insulation safety instrument; High-field electrode must satisfy the insulation against ground requirement, and promptly high-field electrode must use qualified insulating material to come the support fixation high-field electrode, the use insulation rope that has; The use support insulator that has; The use suspension type porcelain vases that have etc., insulation ununified, standard, standard is supported, and uses very inconvenient.
2, high-field electrode generally uses diameter to be not less than the metal tube making of 30mm; For insulation safety instruments such as insulation rod, electroscope are contacted with high-field electrode well; Convenient fixing, the high-field electrode of making has the copper pipe of use, stainless-steel tube, copper bar etc., the shape of making, length, big or small varied; Neither one high-field electrode unified, standard, lack of standardization.
3, after high-field electrode supports through insulation, overhead high about 3m to 5m, insulation rod must use the copper cash winding to link to each other with high-field electrode with a galvanoscopic end.Will could be fastened an insulation rod and a galvanoscopic end on high-field electrode with copper cash through speeling stairway or lift work platform etc. at present, earth terminal also is to twine with copper cash to link to each other with ground, works hard, and wastes time and energy, and work efficiency is low.
The utility model content
The utility model purpose provides an insulating tool vertical hanging device standard, that efficient is high, time saving and energy saving.
The utility model technical scheme: a kind of insulating tool vertical hanging device; Comprise high-field electrode, earthing pole; In the middle of high-field electrode, be provided with penetrating square groove; And on the high-field electrode of penetrating square groove both sides, be furnished with U type groove, and on the U of high-field electrode type groove, hanging with T type auxiliary electrode, the lower end of T type auxiliary electrode is furnished with the screw thread that is connected with insulating tool.
On high-field electrode, be furnished with 15 groups of U type grooves.
High-field electrode is supported by support insulator.
High-field electrode adopts the 500kV support insulator to support.
Earthing pole adopts the circular arc clip.
The utility model possesses following advantage: 1, shortened test period, improved work efficiency.Originally test 15 insulated bars need 4 of personnel, 20 minutes time, adopt this device after, saved the pressurization utmost point and earthing pole and need use the soft copper lead to twine to hang and fix, test 15 insulated bars and only need 2 of personnel, test period is 10 minutes.2, realized the standardized work of test,, improved the dirigibility of test for insulation rod, electroscope experiment work create test science, standard.
Description of drawings
Accompanying drawing is the utility model structural representation.
1-U type groove among the figure, 2-T type auxiliary electrode, the penetrating square groove of 3-, 4-high-field electrode, 5-support insulator, 6-insulation rod, 7-earthing pole.
Embodiment
The high-field electrode of the utility model uses the 500kV support insulator to support and fixes; Adopt the 500kV support insulator; The one, satisfy 220kV insulating tool withstand voltage test requirement; The 2nd, the 500kV insulator mechanical strength is higher, can satisfy the fixing and 20 insulated instrument hanging test job requirements of high-field electrode, makes the whole test device firm in a down-to-earth manner.To the test of 500kV insulator, withstand voltage meets the requirements testing crew under all temps, humidity environment.
High-field electrode global design growth 310cm * wide 20cm * high 5cm, the centre is provided with the penetrating square groove of wide 6cm.Also can use the stainless steel square tube of two 50mm * 50mm to combine, two square tube lengths are 310cm, arrange at a distance of 6cm is parallel, and from then on spacing is passed when satisfying the suspension of insulation rod or electroscope, and two square tube top correspondences have designed 15 groups of U type grooves successively.
Auxiliary electrode adopts diameter 10mm stainless steel bar to make, and is designed to T shape, and T shape auxiliary electrode lower end is designed with internal thread or external thread, is connected with electroscope with insulation rod respectively.At the trial; Take off the metal hook or the galvanoscopic acousto-optic inductor of insulation rod; After the internal thread of T shape auxiliary electrode lower end or external thread are connected, utilize the two ends of T shape auxiliary electrode directly to be suspended on the high-field electrode U type groove, like this through insulation rod or galvanoscopic deadweight; What guaranteed T shape auxiliary electrode and high-field electrode well contacts and hangs firm, has exempted use the soft copper lead to twine loaded down with trivial details.
With the earthing pole that the circular arc clip replaces copper cash to twine, saved the loaded down with trivial details of copper cash winding, improved test efficiency.During test,, use some groups of clips to block insulation rod or electroscope, then through bare copper wire ground connection according to the quantity of insulating tool.
