Background
The application of 10KV switch cabinets in a large number of power systems is directly related to the reliability and safety of power utilization, while in the failure of the switch cabinet, poor contact of contacts accounts for a large proportion, often resulting in burning of the contacts and even the switch cabinet, and the current inspection of contact condition of the contacts usually depends on human experience or over-travel to judge the contact condition, which is very unscientific, resulting in the following aspects of the condition:
1. because no tool for conveniently measuring the contact condition exists at present, the operation contact condition of the switch cabinet is judged only by human judgment during acceptance and only by intuition; moreover, after a period of operation, the original contact position changes due to the deformation of the equipment position and equipment components, causing the contact to heat.
2. When the static contact mounting process is poor during the installation, the moving contact that leads to the switch dolly and the static contact axiality of cubical switchboard are poor, have the unilateral condition of contact, and the switch dolly is hard when operating to the running position, makes the moving contact failure on the one hand, and on the other hand leads to the wearing and tearing aggravation of contact, shortens contact life. Meanwhile, contact resistance of the contact is increased, once load is increased, the contact is heated and burnt, and due to the structure of the switch cabinet, temperature measurement and inspection of the contact cannot be carried out, so that the hidden danger of heating cannot be found and effectively avoided.
3. Due to the special structure of the switch cabinet, the contact condition of the contact cannot be quantified, and the potential safety hazard cannot be tracked, evaluated and processed in time, so that the event is enlarged.
4. Due to the structure of the switch cabinet, the fatigue initial stage of the contact spring can not be found immediately, and the contact spring can not be replaced immediately, even if the contact spring is found, the contact is burnt by overheating and even can not be used.
In summary, when the current switch cabinet trolley is operated to the running position, the contact conditions of the moving contact and the fixed contact cannot be known, so that the contact is heated and burned out, the power supply reliability is reduced, and a safety event is caused.
