Tool for measuring contact depth of contacts of switch cabinet handcart

Abstract

The invention discloses a tool for measuring the contact depth of contacts of a switch cabinet handcart, which comprises a fixed member, a sliding member and a digital display measuring tape, wherein the fixed member is installed at the outer surface of static contact, the sliding member is installed at the outer surface of a moving contact and arranged opposite to the fixed member, and the digital display measuring tape can read automatically. The digital display measuring tape comprises a shell, a measuring tape, a barcode scanner and a display screen, wherein the shell is installed at the inner side of a panel of a switch cabinet handcart body, the measuring tape is arranged in the shell, the barcode scanner is used for carrying out reading on the measuring tape, and the display screen is connected with the barcode scanner and used for displaying the reading; and the measuring tape is provided with a barcode with the adjacent distance being zero. One end of the fixed member is fixed at the tail end of the static contact, the other end of the fixed member is flush with the front end of the static contact, one end of the sliding member is flush with the front end of a plum-blossom-shaped contact, the other end of the sliding contact is connected with an initial end of the measuring tape, the extension length of the measuring tape is at least the axial length of the plum-blossom-shaped contact, and the extension direction of the measuring tape is identical to the axial direction of the sliding member. The tool disclosed by the invention realizes accurate and reliable contact, and the travel of the measuring device can be read, so that the insertion depth of a plum-blossom-shaped contact finger can be judged accurately.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a tool for measuring the contact depth of a switch cabinet handcart contact, which belongs to a small mechanical measuring tool used in an electric power system. Background technique [0002] Metal armored fully enclosed high-voltage switchgear is widely used in power systems. The voltage levels include 10kV, 20kV, and 35kV. It is divided into central type and floor type from the operation mode of the handcart. In terms of the conductive contact method between the handcart and the cabinet , All manufacturers use plum blossom contacts for contact, and the contact method is a point contact method surrounded by surroundings. [0003] Because the high-voltage switchgear is fully enclosed and the space in the contact box is small, even if the handcart is shaken to the working position when the bus is powered off, the operation and maintenance personnel still cannot accurately measure the contact co...

AI Technical Summary

Problems solved by technology

Handcart switch, the process of cranking to the working position cannot be seen or touched by hand, so this original measurement method can only be used, and the size data error is very large, especially in summer high temperature season, when the temperature is above 35 ℃ Vaseline liquefies, and the indentation cannot be seen clearly, or even has no indentation, which brings great difficulties to the on-site measurement and acceptance, and cannot guarantee the accurate and reliable contact of the dynamic and static contacts of the handcart circuit breaker, and is prone to errors
