Description
Technical field
This utility model belongs to electric power transmitting and transforming equipment detection technique field, concretely relates to a kind of for high-tension electricity
Voltage lead wires, end holder is added during gas equipment pressure test.
Background technology
Along with the fast development of power construction, the number of applications of electrical network mesohigh electrical equipment is growing, and enters it
The workload of the high-potting of row increases the most year by year；Electrical equipment carries out the high-pottings such as strict handing-over, sampling observation before coming into operation
The important evidence of putting equipment in service, secondly also carries out customary or diagnostic high-potting in day-to-day operation to electrical equipment, by
Cause in factors such as transformer station's form, device structure, installation sites and between testing equipment and tested device, there is certain space
Distance, high-voltage connection when causing applied voltage test is under gravity in arc lower, and along with the distance of lead-in wire is the longest, it is sagging
Amplitude is the biggest, causes its lead-in wire cannot keep corresponding insulation against ground distance with the distance between device housings and surrounding objects, its
If running into the situation of blowing in secondary pressurization, test lead can swing, and its amplitude of oscillation the longest that goes between is the biggest, easily cause over the ground or
Surrounding objects discharges, and discharge impact easily causes pressurized equipment and damages.Even there is barrier between some tested device and pressurized equipment
Hindering thing, electrical equipment situation such as in cabinet in case, this is accomplished by going between cut-through thing or there is certain space angle situation
Under carry out applied voltage test, secondly causing pressurized line to fix work wastes time and energy and there is unsafe factor, and new cable makes laggard
Can applied voltage test after needing reliably to fix end during row pressure test test.
Testing crew is dried insulant according to the many employings of situation of around limiting to or insulating bar supports and insulating tape or dry at present
The means such as dry tape colligation suspention carry out fixing for several times of test lead, although this traditional fixing means can play fixing
The effect supported, but there is bigger security risk and hidden danger, secondly leads support, colligation etc. are wasted time and energy and are had a strong impact on work
Make efficiency.Such as insulating bar or insulant are fixed insecure easily coming off and are easily caused the person, equipment injury；Insulating tape intensity is not enough
All multi-risk Systems such as easy fracture, tape moisture-sensitive；And when being made in transformator or the test of other equipment leakages, owing to being subject to
To the impact of various extraneous factors, the result of the test error causing us is bigger.Wherein adding voltage lead wires unified fixing is to make
Become the main cause of leakage current difference, and the big testing crew repeated measurement of leakage current difference has a strong impact on work efficiency.
Add voltage lead wires fixed form appliance based on current high pressure equipment to fall behind, have a strong impact on work efficiency, test matter
Amount and reliability, and there is bigger security risk, urgently researching and developing one for this most special can add voltage lead wires
Fixing utensil, to solve high pressure equipment applied voltage test efficiency, the low problem of reliability and the security risk of existence.
Summary of the invention
