Electrical safe distance detecting ruler with signal light

Abstract

The invention relates to an electrical safe distance detecting ruler with a signal light, belongs to the electrical field, and in particular relates to an electrical element detecting device; a measuring ruler which can be contracted and straightened according to circumstances is proposed; the technical solution is as follows: the electrical safe distance detecting ruler with the signal light comprises: a ruler bottom, a ruler top and a supporting rod; the ruler bottom and the ruler top are of hollow tubular structures with one open end, the ruler bottom is provided with an internal thread, abottom end of the ruler bottom is sealed, the ruler top is provided with an external thread, a top end of the ruler top is sealed, the ruler top is slidably arranged on the ruler bottom, the externalthread of the ruler top is adapted to the internal thread of the ruler bottom, the supporting rod is disposed in the ruler bottom and the ruler top, the supporting rod is a retractable rod, the top end of the supporting rod is fixedly 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 rotary knob isarranged on the ruler bottom, the rotary knob drives the supporting rod to rotate via a bevel gear, and a graduated scale is arranged on the ruler bottom and the ruler top.

Description

technical field [0001] The invention relates to an electrical safety distance detection ruler with a signal lamp, 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. Conten...
