Description

Technical Field

[0001] The utility model relates to the technical field of portable switch cabinets, in particular to a portable switch cabinet partial discharge monitoring device. Background Art

[0002] Switch cabinets are commonly used electrical equipment. Insulating parts such as wall bushings, detachable connectors, and voltage transformers in switch cabinets have partial discharges. As solid insulating media and gas insulating media deteriorate, gases such as nitrogen oxides, carbon oxides, and ozone are generated, which diffuse into the interior of the switch cabinet and react with moisture in the air to produce acidic compounds. Similar gases may also appear during the failure of components inside the switch cabinet, further weakening the insulation strength of the equipment and even causing sudden insulation failures in the switch cabinet. Therefore, the fault gas with partial discharge characteristics of the switch cabinet can be monitored. The processor of the prior art analyzes the characteristic gas composition, gas concentration, and defect threat level to facilitate the operation and maintenance personnel to evaluate the internal insulation status of the switch cabinet during the inspection.

[0003] Chinese patent N205882453U discloses a switch cabinet, which mainly relates to the field of electrical equipment, including an outer cabinet, a circuit breaker cabinet and a gas detection control system. The gas detection control system includes a detection host, an alarm and a detector; the circuit breaker cabinet is arranged in the outer cabinet, and the detector includes a single gas detection probe for measuring the SF6 gas concentration and transmitting data to the detection host. The single gas detection probe is arranged in the circuit breaker cabinet. When the SF6 gas concentration detected by the single gas detection probe is less than a preset threshold, the detection host controls the alarm to alarm. The gas detection control system included in the switch cabinet can more effectively solve the problems of untimely leakage detection and uncertainty in the diffusion speed and range of the detected gas in the switch cabinet, maximize the safety of personnel, and avoid electrical accidents. However, the structure of the patent cannot be carried and installed according to needs. The installation is inconvenient and the burden of the staff when traveling cannot be reduced.
