Description

Technical Field

[0001] The utility model belongs to the field of switch cabinet monitoring, and specifically relates to a temperature sensor and an intelligent temperature detection system for a switch cabinet. Background Art

[0002] Switchgear is widely used in distribution networks of power grid companies at all levels and is an important equipment in the power grid.

[0003] Switch cabinet and cable temperature measurement is a routine item in substation operation and maintenance. However, due to the closed structural design of the switch cabinet, the existing temperature measurement technology cannot fully meet the temperature measurement requirements inside the equipment. In the switch cabinet, the contact parts of the moving and static contacts work in a long-term high voltage and high current environment. Due to aging and other reasons, the resistance will gradually increase, causing the contact parts to heat up. In the long run, the heat will further aggravate the aging of the moving and static contacts, thus forming a vicious circle, and eventually leading to power accidents such as switch burning and explosion. Moreover, the current installation structure of the temperature sensor is generally installed in the switch cabinet by screws, and the installation position is limited. The distance from the contact parts of the moving and static contacts that need to be measured cannot be controlled, thereby affecting the measurement accuracy and use range of the temperature sensor.

[0004] In view of this, the present utility model is proposed. Utility Model Content
