Problems solved by technology

Since the rocking handle is located at the end of the meter, if you do not use another hand to press the body of the meter when shaking, or if the hand presses the position improperly, the meter will lose stability and cause errors in the measurement work or affect the safety of the measurement.

Embodiment Construction

[0022] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.

[0023] Figure 1 to Figure 4 Shows an embodiment of the portable hand-cranked megohmmeter fixed integrated box of the present invention. The fixed integrated box includes a box body 1 and a box cover 2 arranged on the top of the box body 1. The box body 1 is provided with a piece in the inner cavity For the first partition 3, the box body 1 is set as a shaker fixing area 11 on one side of the first partition 3 and a tool integration area 12 on the other side. In this structure, the hand-cranked megohmmeter is placed in the fixed area 11 to form a fixation, and tools such as gloves, signs, electroscopes, notebooks, recording pens, and keys between equipment can be displayed and placed in the tool integration area 12. Before the measurement, push the box 1 to the appropriate position, open the lid 2, take out the corresponding tools...

Abstract

The invention discloses a portable hand-cranked megohmmeter fixed integrated box, which comprises a box body and a box cover arranged on the top of the box body. One side is set as a shaker fixed area, and the other side is set as a tool integration area. The fixed integrated box has the advantages of simple structure, convenient and safe use, and can improve measurement stability and accuracy.

Description

Technical field [0001] The invention mainly relates to an auxiliary tool for measuring insulation resistance of electrical equipment, and particularly relates to a portable hand-cranked megohmmeter fixed integrated box. Background technique [0002] The hand-cranked megohmmeter is also called the rocking meter, which is widely used in the power system. A voltage of about 500V / 250V is formed by shaking the handle at a speed of 120r / min and applied between the equipment coil (cable core, etc.) and the "ground" to measure the insulation resistance of electrical equipment. Because the rocking handle is located at the end of the rocking watch, if the body of the rocking watch is not pressed by another hand or improperly pressed by the hand during shaking, the rocking watch will become unstable and bring errors to the measurement work or affect the measurement safety. In addition, the insulation resistance measurement process includes tool preparation, equipment power failure, electri...
