Electrical safety distance detection ruler

Abstract

The invention discloses an electrical safety distance detection ruler, belongs to the electrical field, and particularly relates to an electrical element detection device. A measuring ruler capable ofbeing contracted and straightened according to the conditions is provided. The technical scheme is as follows: the electrical safety distance detection ruler comprises a ruler bottom, a ruler top anda supporting rod; the ruler bottom and the ruler top are both of hollow tubular structures with one open ends; an internal thread is formed in the ruler bottom; the bottom end of the ruler bottom issealed; an external thread is formed in the ruler top; the top end of the ruler top is sealed; the ruler top is arranged on the ruler bottom in a sliding mode; the external thread of the ruler top isadaptive to the internal thread of the ruler bottom; the supporting rod is arranged in the ruler bottom and the ruler top; the supporting rod is a telescopic rod; the top end of the supporting rod isfixedly connected with the top end of the ruler top; the root of the supporting rod is connected with the bottom end of the ruler bottom through a bearing; a knob is arranged on the ruler bottom; theknob drives the supporting rod to rotate through a bevel gear; and graduated scales are arranged on the ruler bottom and the ruler top.

Description

technical field [0001] The invention relates to an electrical safety distance detection ruler, 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 invention...
