Portable SF6 quantitative detection device adaptive to strong electromagnetic field environment

Abstract

The invention provides a portable SF6 quantitative detection device adaptive to a strong electromagnetic field environment. The portable SF6 quantitative detection device comprises a mainboard, a connecting block, a host, a data interface, a wireless communication module, a connecting column, a cable, a connector and a probe body, wherein the left end of the mainboard is connected with the connecting block through a screw; the host is welded on the upper side of the front part of the main board; and the data interface and the wireless communication module are welded in parallel on the left and right parts of the lower side of the front part of the main board. Through the arrangement of a handle, an internal threaded pipe, a protective sleeve, a cleaning pipe, a cleaning cotton block and a protective cap, the probe body which is not used can be well protected, the dust influence is avoided, the internal threaded pipe and the protective sleeve are taken down by holding the handle, the protective cap can be taken down, then the probe body is inserted into the cleaning pipe, and cleaning can be performed through by cleaning cotton block, so that the accuracy of a detection result is ensured, and the cleanliness of the probe body is ensured.

Description

technical field [0001] The invention belongs to the technical field of power distribution equipment inspection, and in particular relates to a portable SF device adapted to a strong electromagnetic field environment. 6 Quantitative detection device. Background technique [0002] use SF 6 The gas density relay is to monitor the SF 6 The main means of pressure change inside the electrical equipment, once the gas pressure inside the equipment drops to the alarm value of the density relay, it means that the equipment has a relatively serious SF 6 In case of leakage, it is necessary to quickly find out the leak point or supply air to the leaking equipment to the rated value before the air pressure continues to drop to the blocking value, otherwise the internal insulation of the equipment will be broken down, resulting in an accident. [0003] Currently SF 6 There are two detection methods when the equipment leaks: (1) Off-line detection, such as bandage method, gas compositio...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a portable SF that adapts to strong electromagnetic field environment 6 Quantitative detection device to address existing SF 6 The quantitative detection device has the problems of long-term hand-carry, which may easily cause operator fatigue, weak ability to adapt to strong electromagnetic field environment, poor protection effect and easy to be affected by the external environment. If it is not used for a long time, it will easily cause the probe to be affected by dust and poor protection effect.
