Abstract

The invention discloses an insulating support for a high-voltage test. The insulating support comprises a base, a strong magnet, an expansion link, an adjusting rod and a support rod, wherein the base is in a semispherical structure, and the strong magnet is arranged in the semispherical base; the expansion link is fixed at the upper end of the base, the adjusting rod is fixed at the top of the expansion link, and the top end of the adjusting rod is movably connected with the support rod; a wire clamping slot is formed in the top of the support rod; a chute is formed in the adjusting rod; a connecting rod is arranged between the adjusting rod and the support rod, one end of the connecting rod is connected with a trough in the adjusting rod through an adjusting bolt, and the other end of the connecting rod is fixed on the support rod. The insulating support provided by the invention is simple in structure, convenient to operate, and is beneficial to obtain accurate test data, so that high voltage leads can be prevented from colliding the device or from being grounded, working efficiency can be improved, and the personal safety of workers can be guaranteed.

Description

A kind of insulating support for high-potting
Technical field
The present invention relates to electric system high-potting field, especially relate to a kind of insulating support for high-potting.
Background technology
At present, in power network, be that the primary equipment of transformer, switch, mutual inductor, lightning rod etc. all will do high-potting to it, check the insulation status of primary equipment.For example, do insulation resistance test, direct current resistance test, medium loss test, AC voltage withstand test, DC voltage withstand test etc. to transformer, will do DC high potential test to lightning rod, mutual inductor be done to the high-pottings such as polarity test.Above-mentioned all tests are to be all that high-voltage connection causes tested device and tests by test lead from different test apparatuses, and trial voltage is general all higher than the working voltage of primary equipment, so very high to the requirement of environmental baseline when test.Staff often supports test lead with insulating bar, and long test lead is wrapped on insulating support rod, and this operation has following deficiency: 1, test lead and radiating fin of transformer or conservator hypotelorism, arcing fault occurs; 2, test lead or insulating bar skew suddenly, inclination, ground connection damage power equipment or test apparatus, the even dangerous personal safety to staff; 3, the set-up time long, staff's inefficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of safe and reliable, simple in structure, easy to use insulating support for high-potting.
To achieve these goals, the present invention is by the following technical solutions:
For an insulating support for high-potting, it comprises base, strong magnet, expansion link, adjusting lever and support bar; Described base is dome-type structure, and strong magnet is arranged in dome-type base; Described expansion link is fixed on base upper end, and expansion link top is fixed with adjusting lever, and adjusting lever top is flexibly connected with support bar; Described supporting bar top is provided with cable clamping interface; On described adjusting lever, there is chute; Between adjusting lever and support bar, be provided with connecting rod, one end of connecting rod is connected with the chute on adjusting lever by adjusting bolt, and the other end is fixed on support bar.
When use, according to the position of test site, adjust the length of expansion link, dome-type base is adsorbed on the correct position of hardware shell or inwall, adjust the position of connecting rod on adjusting lever chute by adjusting bolt, support bar is fixed on set position, high-voltage connection is stuck on cable clamping interface.
Beneficial effect of the present invention is as follows:
1, the present invention can adjust by expansion link and adjusting lever position and the angle of high-voltage connection, make support bar can rotate freely within the specific limits both allocations, with the fixing high-voltage connection of cable clamping interface, high-voltage connection collision equipment or ground connection are avoided, be conducive to obtain accurate test figure, improve work efficiency, ensured staff's personal safety.
2, the present invention is simple in structure, easy to operate, and production cost is low, is applicable to extensive promotion and application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Accompanying drawing mark:
1-base, 2-strong magnet, 3-expansion link, 4-adjusting lever, 5-chute, 6-connecting rod, 7-support bar, 8-cable clamping interface.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
For an insulating support for high-potting, it comprises base 1, strong magnet 2, expansion link 3, adjusting lever 4 and support bar 7.Described base 1 is dome-type structure, and strong magnet 2 is arranged in dome-type base 1.Described expansion link 3 is fixed on base 1 upper end, and expansion link 3 tops are fixed with adjusting lever 4, and adjusting lever 4 tops are flexibly connected with support bar 7.Described support bar 7 tops are provided with cable clamping interface 8.On described adjusting lever 4, there is chute 5; Between adjusting lever 4 and support bar 7, be provided with connecting rod 6, one end of connecting rod 6 is connected with the chute 5 on adjusting lever 4 by adjusting bolt, and the other end is fixed on support bar 7.
When use, according to the position of test site, adjust the length of expansion link 3, dome-type base 1 is adsorbed on the correct position of hardware shell or inwall, adjust the position on the chute 5 of connecting rod 6 on adjusting lever 4 by adjusting bolt, support bar 7 is fixed on set position, high-voltage connection is stuck on cable clamping interface to 8.
