Intelligent temperature measurement static contact device

Abstract

The invention discloses an intelligent temperature measurement static contact device which is of an integrated structure comprising a static contact, a temperature measurement sensor and a metal electricity taking meter band element. The static contact is of a cylindrical structure, the static contact, the temperature measuring sensor and the metal electricity taking meter band element are assembled into a whole set, an annular band groove is formed in the surface of the static contact, and the annular band groove is provided with at least one temperature measuring sensor mounting groove and an annular metal electricity taking meter band fixing groove; and a temperature measurement sensor body is provided with a metal electricity taking meter band fixing groove, the temperature measurement sensor is correspondingly placed in a static contact installation groove, a temperature sensing element in the temperature measurement sensor is in reliable contact with the static contact, and a metal electricity taking ring penetrates through the sensor body and then is reliably fixed in the static contact installation groove. According to the static contact, the appearance size of an original static contact is not changed, and the wireless passive temperature measurement function is achieved; the temperature measuring point is close to the contact surface of the static contact and a tulip contact, so that the actual contact surface temperature can be accurately reflected; and the integrated structural design facilitates detection and replacement.

Description

technical field [0001] The invention relates to the technical field of on-line temperature detection of switch cabinets, in particular to an intelligent temperature measuring static contact device. Background technique [0002] During the long-term operation of the power equipment switchgear, due to the aging, looseness, pollution of equipment components or equipment installation process, overload operation and other problems, it is easy to cause the gap between the connection parts or the contact resistance to increase, which will cause heat under the action of the current, and the temperature will continue. raised. Especially due to the long-term load current and the inrush current when the circuit breaker trolley opens and closes in the working position at the lap joint of the moving and static contacts of the switch. Therefore, the excessively high temperature at the contact joint is a common problem in switchgear, which seriously affects the safe operation of power equ...

AI Technical Summary

Problems solved by technology

Therefore, excessive temperature at the contact joint is a common problem in switchgear, which seriously affects the safe operation of power equipment.

[0003] At present, the temperature measuring components on the market are provided by the secondary equipment manufacturers, and are installed on the original structure of the primary equipment manufacturers. Due to the differences in the switchgear structure of each manufacturer, the secondary equipment manufacturers cannot fully understand the installation of the temperature measuring components. Reliability cannot be guaranteed, there are potential safety hazards, reducing the reliability of switchgear operation, and it is not conducive to later maintenance
