Tramegger special for testing cable

Abstract

The invention discloses a tramegger special for a testing cable. The tramegger comprises a tramegger body. A protective cover is arranged on the surface of the upper end of the tramegger body, the four corners of the protective cover are fixedly installed on the tramegger body through first screws, a dial is arranged on the position, inside the protective cover, of the surface of the upper end ofthe tramegger body, a movable baffle is arranged on the position, on the upper portion of the dial, in the protective cover, a clamping head is fixedly installed on the front portion of the upper endof the movable baffle, the clamping head is a cuboid, and a telescopic cavity communicating horizontally is formed in the clamping head. According to the tramegger special for the testing cable, a convenient handle, an insulated junction box, the protective cover and a connecting ring are arranged, and thus the tramegger is easily held with one hand conveniently to conduct testing; the insulated box is internally wrapped with the wire connecting position, and thus the risk of electric shock is reduced; the dial is effectively protected from being impacted and damaged through the movable baffle; and the tramegger can be placed on a back of a body to move through a connecting shoulder strap conveniently, and the tramegger special for the testing cable is suitable for multi-point testing in an area with a large range.

Description

technical field [0001] The invention relates to the field of megger, in particular to a special megger for testing cables. Background technique [0002] Shake meter, also known as megohm resistance meter, is a megohm resistance meter used to measure the insulation resistance of various electrical equipment. It mainly checks the insulation of motors, electrical appliances and cable lines and measures high-value resistance to avoid heat and When damp, the insulating material ages, resulting in a decrease in insulation resistance, which leads to electrical equipment leakage or short-circuit accidents; however, there are still some deficiencies in the actual use of the existing megger: It is inconvenient to hold the meter body; there are still some conductive parts exposed on the terminal post, and there is a risk of electric shock; the upper dial has no protective device, and it is easy to damage the dial when it is bumped and dropped, affecting use; It is inconvenient to move...
