Carbon monoxide detector and application of detector in voltage test pencil

Abstract

The invention which relates to the technical field of detection discloses a carbon monoxide detector. The carbon monoxide detector comprises a gas sensitive resistor, and an induction thread of the gas sensitive resistor comprises 15% of a mixed metal salt catalyst which comprises 70% of Pt, 25% of Au and 5% of Ag. According to the invention, the carbon monoxide detector which is improved has thecharacteristics of satisfication of the operation environment of voltage testers, low power consumption and small volume, so the combination of the carbon monoxide detector and the voltage test pencil becomes possible. The invention also provides the voltage test pencil which integrates the carbon monoxide detector provided in the invention, and the voltage test pencil which can be integrated with an illumination module can be applied to the voltage test work of dangerous areas. Compared with present voltage test pencils, the voltage test pencil of the invention can be used when light in the work area is not clear, so the electric shock danger of workers is prevented; and the worker can be timely promoted to rapidly depart to guarantee the safety when carbon monoxide which has a standard-exceeded concentration may initiate the explosion danger and the positioning danger once carbon monoxide encounters electric sparks.

Description

technical field [0001] The invention relates to the technical field of detection, and is especially suitable for detecting toxic gases. Background technique [0002] In the on-site environment where electrical appliances need to be overhauled and maintained, sometimes there may be toxic gases that are harmful to the human body, such as carbon monoxide. In this kind of site, due to the flammability and toxicity of carbon monoxide gas, it poses a certain threat to the health and life of the workers. In addition to the insufficient lighting conditions and lack of light source in the dangerous working environment, when working in a small electrical cabinet, it is very easy to cause the danger of electric shock to the staff who cannot see clearly. [0003] Existing carbon monoxide detectors basically use large battery-powered contact combustion gas sensors and electrochemical gas sensors to heat the sensing electrode wire to a high temperature of 300°C to 400°C through power su...

Problems solved by technology

[0006] 1. Existing carbon monoxide detectors consume a lot of energy and are bulky

[0007] 2. Due to the large energy consumption and large volume of the existing carbon monoxide detectors, it cannot be integrated with the electric test pen. Even if the two are combined into one, due to the large volume, it will be difficult for the operator to grasp during the electric test process. The detection tool cannot detect leakage in a narrow location; if the operator is allowed to carry the two separately, since the operator holds the electric test pen and observes the test pen neon tube and the detection point, at this time, the energy is concentrated on the test pen at the hand. If you have to always pay attention to whether the carbon monoxide detector carried on your body detects toxic gas, it will cause the operator to be easily distracted, and the possibility of missed detection will occur, and carrying it separately will increase the burden on the operator, which is not conducive to the complex environment. detection
