Insulation detection sensor for railway locomotive high voltage pipe casing

Abstract

The invention relates to the technical field of insulation sensors, and discloses an insulation detection sensor of a high-voltage pipe sleeve for locomotive. The insulation detection sensor comprisesa fixed floor, wherein a sensor body is fixedly arranged at the top of the fixed floor, an alarm is fixedly arranged at the top of the sensor body, and a hexagonal sensor is fixedly arranged at a right side of the alarm. In the insulation detection sensor of the high-voltage pipe sleeve for the locomotive, a heat sink is arranged at one end of the insulation detection sensor of the high-voltage pipe sleeve, an air inlet is formed in the corresponding other end, hot air in the insulation detection sensor of the high-voltage pipe sleeve is discharged by the heat sink, fresh cold air is furthersunken through the air inlet, so that the effect of cold air circulation is achieved, a relatively low temperature of an inner cavity of the insulation detection sensor of the high-voltage pipe sleeveis stably maintained, an internal component is prevented from being affected by thermal loss, and a promotion effect on the service lifetime of the insulation detection sensor of the high-voltage pipe sleeve also can be achieved once the working property of the component is improved.

Description

technical field [0001] The invention relates to the technical field of insulation sensors, in particular to an insulation detection sensor for high-voltage pipe sleeves of railway locomotives. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, and recording. and control requirements. [0003] Due to the integration of the Hall current sensor and the insulation detection module, the existing high-voltage bushing insulation detection sensor is relatively expensive, so there will be incidents of theft of the high-voltage bushing insulation detection sensor. In addition, the sensor is small in size, but The sensors and components integrated inside it will generate a lot of heat, and the small heat dissipation vents c...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a railway locomotive high-voltage pipe sleeve insulation detection sensor, which has the advantages of a cooling device to accelerate cold air circulation to reduce heat loss of components, infrared detection and an alarm device with superior anti-theft performance, and solves the traditional problem. The high-voltage bushing insulation detection sensor cannot dissipate the internal heat of the high-voltage bushing insulation detection sensor in time during the heat dissipation process, resulting in serious heat accumulation in the inner cavity of the high-voltage bushing insulation detection sensor, which in turn affects the service life of the high-voltage bushing insulation detection sensor The problem
