Embodiment 1

[0024] Such as figure 1 The secondary voltage extracting device shown is used to obtain the voltage of the secondary terminal, including: a support plate 10 provided with an insertion hole 11, connected to the support plate 10 and used to cooperate with the outer periphery of the secondary terminal There are at least four clamping jaws 20 , a handle portion 30 for controlling the clamping jaws 20 to be clamped or released, and a joint assembly 40 matched with the insertion hole 11 .

[0025] The secondary voltage extraction device of this embodiment effectively solves the problem of voltage signal extraction from the secondary terminal of the voltage transformer in the live test of the lightning arrester in the substation, and solves the problem that the clips used in the traditional secondary voltage extraction work cannot accurately and quickly perform voltage extraction, and the efficiency is low. In addition, the clip is easy to fall or short-circuit, resulting in unreliab...

Embodiment 2

[0037] The structure and principle of this embodiment are similar to that of Embodiment 1, the difference lies in that the jaw 20 of this embodiment is rotatably connected with the support plate 10 . That is, the relative rotation of the jaws 20 and the support plate 10 can be achieved through hinges or other rotational connections, so that the gripper 30 drives the rotation of the jaws 20 to realize the clamping or loosening function of the jaws 20 .

Abstract

The invention discloses a secondary voltage extraction device. The secondary voltage extraction device is used for obtaining voltage of a secondary terminal, includes a supporting plate provided withan inserting-connection hole, at least four clamping jaws connected with the supporting plate and used for being matched with the periphery of the secondary terminal, a hand-held part used for controlling the clamping jaws to be clamped or released and a joint assembly matched with the inserting-connection hole. The secondary voltage extraction device effectively solves the problem of obtaining voltage signals from a secondary terminal row of a voltage transformer in the live test of a lightning arrester in a substation, and solves the problem that potential safety hazards are caused due to unreliable fixing due to the fact that clips are prone to being fallen and short-circuited due to the fact that the clips adopted in the traditional secondary voltage extraction work cannot accurately and quickly perform voltage extraction, and the efficiency is low.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a secondary voltage extraction device. Background technique [0002] At present, in order to calculate the resistive component of the leakage current during the live test of the arrester in the substation, the voltage must be extracted from the secondary terminal block of the bus PT and the leakage current of the arrester for phase angle comparison. Therefore, a special arrester live tester must be used to connect the PT secondary The dedicated A630 and N600 terminals on the secondary terminal block obtain a secondary voltage of 60V. Most of the current lightning arrester live testers are equipped with some small sharp-nosed wire clips. Due to the different construction years of each substation, the size of the secondary terminal block is different, and some terminal blocks have small apertures, and it is difficult to touch the terminals after the wire clip is fixed. The...
