Intelligent sulfur hexafluoride biotoxicity test device

Abstract

The invention provides an intelligent sulfur hexafluoride biological toxicity testing device. The intelligent sulfur hexafluoride biological toxicity testing device is characterized in that a poisoning box is made of organic glass with good light transmission; a high-definition camera is arranged on the outer wall of the poisoning box; the poisoning box is internally provided with a displacement sensor and is additionally provided with an air pump, a buffer tank, a recycling tank, a controller, an alarm and a plurality of airflow control modules; each airflow control module comprises a flow control valve and a constant difference pressure-reducing valve, which are connected in parallel; the signal output ends of the high-definition camera and the displacement sensor are connected with the controller; an air inlet end of each gas mixing module is correspondingly connected with an oxygen bottle and a sulfur hexafluoride gas bottle through a pipeline provided with an electronic flow meter and the airflow control module respectively; an air outlet end of each gas mixing module is communicated with the poisoning box through a pipeline with a tee joint and an air inlet pipe in sequence; an air outlet of the poisoning box is connected with the buffering tank and the air outlet end of the buffering tank is connected with the recycling tank through a pump; and the output end of the air pump is connected with the tee joint and the output end of the air pump is connected with the alarm, the air pump, the pump and the electronic flow meter; and meanwhile, alarming and movement frequencies and an image signal are wirelessly and remotely transmitted.

Description

technical field [0001] The invention relates to an intelligent sulfur hexafluoride biological toxicity test device, which belongs to the technical field of sulfur hexafluoride toxicity test. Background technique [0002] Currently commonly used SF 6 One gas biotoxicity test can only complete the inspection of one bottle of gas, and the test period is long. Generally, continuous observation is required for 72 hours. Staff are required to be on duty to observe the condition of the mice continuously, and the test workload is relatively large. With the development of power grid construction, there are more and more large-capacity electrical equipment such as UHV and EHV. 6 The demand for gas is increasing, the test workload is huge, and there is an urgent need for the existing SF 6 The gas biological toxicity test was improved and perfected to form a fast, efficient, effective and reliable test method, which completely solved the problem of SF 6 The problem of gas biotoxicity...
