Pull rod type substation fire alarm probe detecting device

Abstract

The invention discloses a pull rod type substation fire alarm probe detecting device, which comprises a telescopic rod, a smoke collecting hood fixed at one end of the telescopic rod, and a positioning needle arranged in the smoke collecting hood. One end of the telescopic rod is hinged to the smoke collecting hood, and the other end is sleeved with an anti-slip sheath. The smoke collecting hood comprises a bottom surface and four side surfaces which are fixedly connected with four sides of the bottom surface. The cross-section shape of the smoke collecting hood is rectangular, the cross-section shape is increased in a direction away from the bottom surface, and vent holes are formed in the side surface. The pull rod type substation fire alarm probe detecting device has the advantages of simple structure, convenient use and high detection efficiency, can effectively reduce the detection difficulty of a fire alarm probe in a transformer room, improves the detection efficiency, generatesfew smoke during the detection process, cannot cause dust falling, and is safer in use.

Description

technical field [0001] The invention relates to the field of substation safety, in particular to a rod-type substation fire alarm probe detection device. Background technique [0002] A substation is a place in a power system that transforms voltage and current, collects, receives, and distributes electric energy. As the hub of power grid circuit transmission, the substation plays a very important role in the normal operation of the power grid. Therefore, stable and reliable requirements are put forward for the safe operation of its substation equipment. [0003] Substation inspection is an important guarantee for its safe operation. The inspection of substations is that the operation and maintenance personnel observe whether there is any abnormality in the operation status of the equipment through regular inspections, such as whether there is any change in color, whether there are sundries, whether the pointer indication is normal, whether the sound of the equipment is no...

AI Technical Summary

Problems solved by technology

Fire alarm probes are mostly installed on the roof of houses over 4 meters above the power distribution room and relay protection room. When checking whether the status is good or bad, it is necessary to conduct on-site inspections for each fire alarm probe. Usually, a climbing ladder or an A-frame ladder is required for inspection. And other tools to carry out the climbing detection, and at the same time assist the staff to hold the ladder, usually two people cooperate to operate, the detection speed is very slow

Moreover, the installation height of the fire alarm probe is generally high, and it is very difficult to detect in the substation equipment room with many electrical equipment, and the height is often insufficient and the distance between the operating point and the monitoring point is too long

During the torch simulated smoke test, the test smoke diffuses freely, which is poorly targeted and prone to chain alarms, resulting in the inability of testers to obtain real data. After the test smoke diffuses, it is not easy to disperse in the substation room, and it is easy to cause indoor environmental pollution.
