Embodiment 1

[0044] A temperature measuring device for a trolley switch of an electric high-voltage switchgear, comprising a switchgear 43 and an infrared temperature sensor 52 arranged in the switchgear for detecting the switch temperature, the infrared temperature sensor is connected to a programmable controller 53, and the programmable control The device is connected with the sound and light sound and light alarm device 51, the programmable controller is connected with the blower, the switch cabinet is provided with a dust removal system, and the dust removal system includes a first dust removal mechanism, which is connected to the first end of the first dust removal mechanism. The energy conversion mechanism, the first regeneration mechanism communicated with the second end of the first dust removal mechanism, the sedimentation mechanism communicated with the energy conversion mechanism, the dust accumulation module arranged at the lower part of the sedimentation mechanism, and the dust ...

Embodiment 2

[0056] Embodiment 2, which is different from Embodiment 1 in that: the regeneration pipeline 2, the regeneration discharge pipe 21, and the first air intake pipe 22 are all equipped with a detection module 19;

[0057] The detection module 19 includes a flow rate sensor 192 , a dust sensor 191 and a temperature sensor 193 .

[0058] The first regeneration mechanism adopted in this embodiment includes a regeneration pipeline communicated with the discharge mechanism, solenoid valves arranged at both ends of the regeneration pipeline, a regeneration supercharger arranged in the middle of the regeneration pipeline, and a The regeneration discharge pipe at the lower part of the dust collector; the airflow can be pressurized by the regeneration supercharger to ensure that there is a high-speed airflow to clean the dust collector during back-blowing and dust removal, which can greatly reduce the amount of back-blowing gas and ensure The effect of overall cleaning; the energy convers...

Embodiment 3

[0059] Embodiment 3: The difference between it and Embodiment 2 is that: the first dust removal mechanism, the energy conversion mechanism, the first regeneration mechanism, the sedimentation mechanism, the dust accumulation module, the absorption mechanism, the discharge mechanism, the circulation mechanism, and the unloading module are all compatible with The signal interconnection of the control modules arranged on the outer wall of the dust collector;

[0060] The control module is PLC or personal computer.

[0061] The adsorption turntable includes two ring-shaped sealing plates 231, a cylindrical channel 232 that is arranged between the two ring-shaped sealing plates 231 and matches the discharge pipe, and connects the mandrel 237 and the ring. A plurality of support arms 233 between the shaped sealing plates 231;

[0062]The adsorption module is arranged in the cylindrical channel 232, and the sealing ring 235 matched with the annular sealing plate 231 is arranged on t...

Abstract

The invention discloses a temperature measuring device for a power high voltage switch cabinet trolley switch. The temperature measuring device comprises a switch cabinet and an infrared temperature sensor which is arranged in the switch cabinet and is used for detecting the temperature of the switch. The infrared temperature sensor is connected with a programmable controller. The programmable controller is connected with a sound and light alarm. The programmable controller is connected with a blower. The switch cabinet is equipped with a dust removing system. The dust removing system comprises a first dust removing mechanism, a transduction mechanism communicated with a first end of the first dust removing mechanism, a first regeneration mechanism communicated with a second end of the first dust removing mechanism, and a sedimentation mechanism communicated with the transduction mechanism. For the phenomenon that waste gas enters a natural environment due to the fact that an existing dust removing system cannot carry out efficient utilization on waste, through mutual cooperation effect of various modules, the waste gas can be recycled efficiently, substances in the waste gas can be recycled, and the pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a temperature measuring device for a trolley switch of an electric high-voltage switch cabinet. Background technique [0002] According to incomplete statistics, at present, the failure of high-voltage electrical switchgear equipment caused by external environment changes accounts for 62% of the overall equipment failure, design and device defects account for 18%, use and maintenance factors account for 11%, and other factors account for 9%. External environmental factors have become one of the important reasons affecting the stable operation of electrical equipment. [0003] Conductive dust (such as coal dust, metal dust, etc.) deposits on the conductor or enters the machine or instrument will cause safety hazards and affect the service life of the machine or instrument. Installing a ventilator is the main way to ventilate the switchgear. At present...
