Embodiment Construction

[0015] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0016] Such as figure 1 Shown, a kind of low-voltage load test device comprises a 2-meter-long insulating rod 1, a clamp-type current transformer 2 arranged at the top of the insulating rod, an ammeter 4 arranged at the lower end of the insulating rod 1, and an ammeter 4 arranged at the insulating rod 1. The handbrake 3 at the lower end, the handbrake 3 is connected to the clamp current transformer 2 to control its opening and closing through the handbrake line, and the clamp current transformer 2 is connected to the ammeter 4 through the current secondary line 5, and the clamp current transformer 2 is connected to the current secondary line 5. The transformer 2 and the ammeter 4 are respectively the clamp current transformer part and the ammeter part of the clamp ammeter.

[0017] When working, the operator holds the lower end of the in...

Abstract

The invention provides a low voltage load test device. The low voltage load test device comprises an insulating rod, a clamp-shaped current transformer which is arranged at the top of the insulating rod, an ammeter which is arranged on the lower end of the insulating rod, and a handbrake which is arranged on the lower end of the insulating rod. The handbrake is connected with the clamp-shaped current transformer through a handbrake line to control the clamp-shaped current transformer to switch on and off. The clamp-shaped current transformer is connected with the ammeter through a current secondary line. The low voltage load test device has the advantages of scientific design, high work efficiency and high safety coefficient.

Description

technical field [0001] The invention relates to a test device, in particular to a low-voltage load test device. Background technique [0002] The low-voltage load test of distribution transformers is an essential and important task every day, and each transformer should be tested 2-3 times a day. In recent years, with the expansion of the urban framework, the electricity consumption of various industries has increased sharply, and the distribution transformers have also gradually increased. , under the supervision of one person, the surveyor needs to climb on the 3.5-meter-high live distribution transformer bench for operation, which is risky, close contact with wires, easy to get electric shock and burns, and climbing up and down, it takes a very long time and a long time of labor Very prone to safety accidents. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The object of ...
