Embodiment 1

[0025] figure 1 It is a structural diagram of a current measuring device disclosed in the embodiment of this application.

[0026] Such as figure 1 The current measuring device shown includes a clamp meter 10 , a retractable insulating handle 20 , a coupling 23 , a pull wire 30 and a handle 40 . The clamp ammeter 10 is hinged to the upper end 21 of the insulating rod 20 through a coupling 23 , and the clip 113 of the clamp ammeter 10 for opening the clamp head 11 is connected to the handle 40 through a pull wire 30 .

[0027] Clamp ammeter 10 comprises pincer head 11, and pincer head comprises fixed bayonet 111 and movable bayonet 112, and when movable bayonet 112 moves, pincer head 11 will open, and now will open pincer head 11 block and wait for The wire measured, then close the clamp head 11, just can measure. The movable bayonet 112 is provided with a locking member 113 for moving the movable bayonet 112 to open the pliers 11 .

[0028] The insulating handle 20 is a ho...

Embodiment 2

[0034] figure 2 It is a structural diagram of another current measuring device disclosed in the embodiment of the present application.

[0035] In the first embodiment, the clamp 113 is directly pulled by the pull wire 30 to move the movable bayonet 112 to complete the action of opening the pliers 11 . In this embodiment, a pressure plate 50 is added, and the clamp 113 is pushed by the pressure plate 50 to open the pliers head 11 .

[0036] Such as figure 2 As shown, a first support 31 is provided on the clamp body of the clamp ammeter 10, and one end of the first support 31 is fixedly connected with the body of the clamp ammeter 10, and the other end is provided with a pressing plate 50, and the fixed end 51 of the pressing plate 50 is connected to the clamp body of the clamp ammeter 10. The first bracket 31 is connected by a rotating shaft. The first bracket 31 can also be disposed on the insulating handle 20 .

[0037] The shape of the pressing plate 50 is preferably ...

Embodiment 3

[0040] image 3 It is a structural diagram of another current measuring device disclosed in the embodiment of the present application.

[0041] In the second embodiment, when the angle between the ammeter clamp 10 and the insulating handle 20 is at a certain angle, pulling the pressing plate 50 may cause the pressing plate 50 to be far away from the clip 113 of the ammeter clamp 10, so that the pressing plate 50 cannot be aligned with the clip. 113 exerts pressure to open the clamp head 11. At this time, it is necessary to repeatedly adjust the angle of the clamp ammeter 10 and the insulating handle 20, which is inconvenient to use. To solve this problem, a guide hole 321 is added on the basis of the second embodiment.

[0042] Such as image 3 In the shown current measuring device, a second bracket 32 ​​is provided on the side of the clamp-on ammeter 10 near the fixed bayonet 111 of the clamp head 11, and one end of the second bracket 32 ​​is fixedly connected to the clamp-...

Abstract

The invention discloses a current measuring device. The current measuring device comprises a clip-on ammeter, an insulating handle and a pull wire, wherein the clip-on ammeter is provided with a tongs head, the tongs head comprises a fixed bayonet and a moving bayonet, and the moving bayonet is provided with a clamping piece used for opening the tongs head; the upper end of the insulating handle is hinged to the clip-on ammeter; the head end of the pull wire is connected with the clamping piece and used for pulling or pressing the clamping piece to open the tongs head. The current measuring device can make the clip-on ammeter close to overhead electrical equipment by the utilization of an insulating rod to perform measurement, a measurement worker does not need to be close to the overhead electrical equipment for measurement, and the current measuring device is more convenient and safe to use in operation.

Description

technical field [0001] The present application relates to the technical field of current measurement, and more specifically, to a current measurement device. Background technique [0002] In the daily maintenance of power circuits, it is often necessary to measure the current value of high-altitude power equipment. But at present, when measuring the current of these high-altitude power equipment, maintenance personnel need to climb to a high place, get close to the power equipment, and then use a clamp ammeter to measure. This measurement method is prone to personal fall accidents or electric shock accidents. Contents of the invention [0003] In view of this, the present application provides a current measuring device, so as to realize the measurement of high-altitude power equipment more conveniently and safely. [0004] In order to achieve the above purpose, the proposed scheme is as follows: [0005] A current measuring device comprising a clamp ammeter, an insulatin...
