Electrical safety distance measuring device

Abstract

The invention discloses an electrical safety distance measuring device, belongs to the electric field, and particularly relates to an electrical element detection device. A measuring scale capable ofbeing retractable and straightened according to the situation is provided. The technical scheme is as follows: the electrical safety distance measuring device comprises a scale bottom, a scale top anda supporting rod, wherein the scale bottom and the scale top are respectively of a hollow tubular structure with one end open; the scale bottom is provided with an internal thread, and the bottom endof the scale bottom is sealed; the scale top is provided with an external thread, and the top end of the scale top is sealed; the scale top is arranged on the scale bottom in a sliding mode, and theexternal thread of the scale top is matched with the internal thread of the scale bottom; the supporting rod is arranged in the scale bottom and the scale top; the supporting rod is a telescopic rod;the top end of the supporting rod is fixedly connected to the top end of the scale top; the root of the supporting rod is connected to the bottom end of the scale bottom through a bearing; a knob is arranged on the scale bottom; the knob drives the supporting rod to rotate through a bevel gear; and a graduated scale is arranged on each of the scale bottom and the scale top.

Description

technical field [0001] The invention relates to an electrical safety distance measuring device, which belongs to the electrical field, and in particular relates to an electrical component detection device. Background technique [0002] In electrical equipment, the electrical safety distance is an important parameter for whether the electrical equipment can operate safely in the power system. The safety distance cannot be guaranteed due to inaccurate measurement, which may cause insulation damage and cause equipment operation accidents. [0003] The electrical components are installed in the electrical cabinet. Due to the small space in the electrical cabinet, the installation and arrangement of electrical components are limited by the space. Many positions that need to be tested are blocked or hindered by the electrical components in front. It is difficult for inspectors to use them directly due to the limited space. ruler for accurate measurement. Contents of the inventio...
