Embodiment Construction

[0044] In order to facilitate the understanding of the technical content of the present invention, the technical solutions thereof will be further described below in conjunction with the accompanying drawings.

[0045] like figure 1 and figure 2 A portable lightning arrester test box shown includes a lower box body 1 , two telescopic insulating rods 2 , a cover plate 3 , a limit plug 4 , a support platform 5 and an upper box body 6 . The support platform 5 is made of metal, and the lower box body 1, the cover plate 3, the limit insert block 4 and the upper box body 6 are all made of insulating material.

[0046] like figure 1 and figure 2 As shown, the upper end surface of the lower box 1 is provided with strip-shaped grooves on the left and right sides, and the left or right sides of the strip-shaped grooves extend to the left and right side edges of the lower box respectively. On the upper end surface of the lower box body 1, vertically extending connecting slots 12 are ...

Abstract

The invention discloses a portable lightning arrester testing box. The upper end face of a lower box body is provided with a square sunken groove, and the left end of a telescoping insulating rod is hinged to the left end of the square sunken groove and can be turned upwards by 90 degrees in a vertical plane. A cover plate is disposed at the upper end of the square sunken groove, and cooperates with the square sunken groove through employing a sliding rail cooperation structure. The cover plate is provided with a positioning clamping bock, and an outer vertical end face in a left/right direction of the positioning clamping block is provided with an arc-shaped notch. A free end of the telescoping insulating rod is provided with a fixing device. The right end of the square sunken groove is provided with a wire duct which extends downwards, and a part, corresponding to the center of the right side surface of the wire duct, of the right side of the wire duct is provided with a limiting slot cooperating with a limiting insertion block. The box is simple and compact in structure, enables a part to have a plurality of functions, and reduces the number of used parts. Moreover, the box is portable, can achieve on-site testing of a lightning arrester after power failure, does not need to consume a large amount of money to purchase new equipment, shortens the power-failure inspection and maintenance time for testing, and meets the requirements for expanding power supply and broadening marketing scope for the high-quality services of a power enterprise.

Description

technical field [0001] The invention relates to the relevant technical field of an auxiliary device for detection and testing of lightning arresters, in particular to a portable lightning arrester test box. Background technique [0002] Surge arresters are electrical appliances used to protect electrical equipment from transient high voltage hazards and limit the freewheeling time and freewheeling amplitude. During the maintenance of electrical facilities of the power supply company, a large number of arresters are removed and replaced every year. The removed surge arresters generally need to be tested, and the qualified ones will be recycled and reused. However, due to the lack of on-site test devices, the disassembled arresters often need to be transported to the laboratory for testing, and at the same time, new arresters are replaced on the substation facilities. The surge arresters that have passed the test are stored. It is transported back to the facility site for r...
