What impact does terminal block burnout have on the safety of an explosion-proof distribution box?
With the development of industrialization, the range of applications for terminal blocks has become increasingly broad. However, improper use of a large number of terminal blocks has led to frequent incidents of terminal block burnout, posing a serious hazard to the safety of explosion-proof distribution boxes.。
Most causes of terminal block burnout in explosion-proof distribution boxes are similar. Based on the burnout conditions, it can be found that the main terminal blocks inside explosion-proof distribution cabinets often carry large currents, making them prone to heating and burnout faults. Cage-type terminal blocks, especially spring-loaded cage-type terminal blocks, are more frequently subject to burnout.。
The first is heating and burnout of terminal blocks on electrical components.。This can cause heating and burnout of main contactors, air switches, and other related electrical components in one or two circuits. There are two main reasons for burnout.。First, external factors cause vibration inside the distribution cabinet, leading to loose connections between terminal blocks and electrical components, with continuously decreasing clamping force, resulting in increased contact resistance; second, poor crimping between terminal blocks and the conductive bodies of wiring increases resistance, causing terminal blocks of electrical components to heat up and burn out during prolonged energization.。
Burnout of spring-type terminal blocks and its causes.。Spring-type terminal blocks feature a compact structure and convenient wiring. However, precisely because of their tight connection, burnout inside spring-type terminal blocks is not easily detected on the surface, resulting in relatively severe burnout.。
