Abstract

The utility model provides an electric leakage detecting device of a live low-voltage line. The electric leakage detecting device comprises a clip-on current transformer, a movable arm of the clip-on current transformer, an insulating support, an insulating brake bar, a rope, a processor, and a display screen. The insulating support is used for placing the clip-on current transformer. The length of the insulating brake bar can be adjusted. The rope is used for controlling the movable arm of the clip-on current transformer. The processor is used for processing data measured by the clip-on current transformer. The display screen is used for displaying results. The clip-on current transformer is disposed on the top of the insulating support. The insulating brake bar is disposed on the bottom of the insulating support. The rope is disposed on the bottom of the movable arm. The clip-on current transformer, the processor, and the display screen are connected electrically and successively. The electric leakage detecting device of a live low-voltage line prevents power cut and the process of pole climbing operation which are caused by circuit detection, reduces errors caused by human factors, and has characteristics of easy manipulation and convenient use.

Description

Charged low-voltage circuit earth detector

Technical field

The utility model relates to the servicing unit field, particularly a kind of charged low-voltage circuit earth detector that a kind of low-voltage circuit detects.

Background technology

Low voltage electric network ground connection, trees short, insulator damage or inefficacy because lead fractures, the inner ground connection of consumer can make the circuit of operation electric leakage or grounding phenomenon occur, cause line tripping, influence the normal electricity consumption of client.In these faults, lead fracture ground connection, trees short fault can in time be found to handle by artificial line walking inspection; The inner ground connection of consumer can be detected by the clamp on amperemeter of band milliampere shelves and find, fixes a breakdown.But, if because of line insulator damage or inefficacy, cause line electrical leakage, check very trouble, should rule of thumb analyze, with megohmmeter the whole piece line test be insulated again, also will step on bar to faulty section and test investigation one by one, whole process wastes time and energy, and can't satisfy high-quality and efficient service.

The utility model content

Technical problem to be solved in the utility model provides the charged low-voltage circuit earth detector that a kind of quick and easy detection line insulator damages.

To achieve these goals, the technical solution adopted in the utility model provides a kind of charged low-voltage circuit earth detector, comprise split core type current transformer and lever arm thereof, also comprise for the insulating support of placing described split core type current transformer, can regulate the insulation restrictor bar of length, the rope that is used for control split core type current transformer lever arm, the processor of the data of measuring for the treatment of described split core type current transformer and be used for showing result's display screen, described split core type current transformer is arranged at described insulating support upper end, described insulation restrictor bar is arranged at described insulating support lower end, described rope is arranged at described lever arm lower end, described split core type current transformer, processor and display screen are electrically connected successively.

The major advantage of charged low-voltage circuit earth detector of the present utility model has:

1. avoided having a power failure and stepping on the bar operation, reduced the hidden danger of the charged work of staff,, be the good tool of being engaged in repair based on condition of component work. the electrician that can not step on the bar operation also can check low-voltage circuit, and work efficiency can improve more than 80%.

2. utilize the field calibration function, can in time find and realize accurate measurement, error can be controlled below ± 0.5%.

3. simple to operate, can 1 people operate, also can 2 people carry out, the data of measuring are directly handled, generate the result, be convenient to record and statistics, reduced the error that human factor produces, easy to use.

Description of drawings

The structural representation of the charged low-voltage circuit earth detector that Fig. 1 provides for the utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

As shown in Figure 1, a kind of charged low-voltage circuit earth detector of the present utility model, comprise split core type current transformer 1 and lever arm 2 thereof, also comprise for the insulating support 3 of placing described split core type current transformer, can regulate the insulation restrictor bar 4 of length, the rope 5 that is used for control split core type current transformer lever arm 2, the processor 6 of the data of measuring for the treatment of described split core type current transformer and be used for showing result's display screen 7, described split core type current transformer 1 is arranged at described insulating support 3 upper ends, described insulation restrictor bar 4 is arranged at described insulating support 3 lower ends, described rope 5 is arranged at described lever arm 2 lower ends, described split core type current transformer 1, processor 6 and display screen 7 are electrically connected successively.

The concrete job step of the charged low-voltage circuit earth detector that the utility model provides is:

1. the restrictor bar 4 that will insulate is adjusted to suitable height, split core type current transformer 1 can be stuck on the lead to be measured with operating personnel to be as the criterion;

2. lift insulation restrictor bar 4, pulling rope 5 uses two split core type current transformers 1 to be stuck on the same lead of line insulator both sides, and pulling rope 5 drives lever arm 2 work, closed split core type current transformer 1 bayonet socket.

3. leakage current and the line current data after display screen 7 reads treated device 6 processing are preserved data or record related data as required.

4. pulling rope 5 takes off split core type current transformer 1, carries out next measurement point and measures.

5. task finishes, and packs up insulation restrictor bar 4 and pertinent instruments.

In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.
