Circuit joint temperature sensing out-of-limit alarm

Abstract

The invention discloses a line joint temperature sensing out-of-limit alarm, and relates to the technical field of cable monitoring devices. The main body frame is integrally of a rectangular structure, a mounting frame of a U-shaped structure is welded and fixed to the top end of the middle position of the main body frame, two longitudinal supporting plates are symmetrically welded between the middle sections of the main body frame, and a mounting ring is rotatably mounted between the middle sections of the two longitudinal supporting plates; a buzzer alarm and an electric controller are locked and mounted at the bottom of the mounting frame at intervals, and the electric controller is electrically connected with the infrared temperature sensor and the buzzer alarm; and the four semicircular clamping rings slide oppositely and are clamped at the two ends of the cable joint. According to the invention, the driving part and the semicircular clamping ring can drive the infrared temperature sensor to synchronously rotate and switch the use state through linkage engagement when rotating to switch the use state, so that the problems that the infrared temperature sensor needs to be additionally and manually folded and unfolded during use, and the operation is troublesome and time-consuming are solved.

Description

technical field [0001] The invention relates to the technical field of cable monitoring devices, in particular to a temperature-sensing limit alarm for line joints. Background technique [0002] In order to prevent the power distribution line from being burnt due to overcurrent or poor contact overheating, resulting in a power outage, affecting the safe use of electricity by customers, and endangering the safe operation of the power grid, it is necessary to design a line joint temperature limit alarm To monitor the cable joints. [0003] Most of the clamping installation structure and infrared temperature sensor on the existing cable monitoring device are installed with static protruding supports, which cannot be flexibly rotated or slid and contracted, resulting in a large space occupied by the supports, which is not convenient for mass transportation in boxes. And even if there are a few devices with clamping installation structures and infrared temperature sensors that c...

Problems solved by technology

[0002] In order to prevent the power distribution line from being burnt out due to overcurrent or poor contact overheating, resulting in a power outage, affecting the safe use of electricity by customers, and endangering the safe operation of the power grid, it is necessary to design a line joint temperature over-limit alarm To monitor the cable joints

[0003] Most of the clamping installation structure and infrared temperature sensor on the existing cable monitoring device are installed with static protruding supports, which cannot be flexibly rotated or slid and contracted, resulting in a large space occupied by the supports, which is not convenient for mass transportation in boxes. And even if there are a few devices with clamping installation structures and infrared temperature sensors that can shrink and hide, most of their driving mechanisms cannot be linked and combined, and manual operations in multiple steps are required to complete the shrinking and stretching operations, which is troublesome, time-consuming and inconvenient to use.
