Description

Technical Field

[0001] The utility model relates to the technical field of anti-seismic power distribution cabinets, in particular to a high and low voltage power distribution cabinet with a vibration reduction function. Background Art

[0002] Due to the wide range of application scenarios of high and low voltage distribution cabinets, their operating environment is diverse and complex. They may be installed in indoor distribution rooms or exposed to outdoor environments such as substations or construction sites. The indoor environment may have problems such as temperature and humidity changes, and poor ventilation conditions; while the outdoor environment may face harsh weather conditions, such as high temperature, low temperature, sun, rain, wind and sand, etc., and may also be affected by mechanical stress such as vibration and impact. For example, in some substations close to traffic arteries, distribution cabinets may be affected by the vibration generated by vehicle driving. In factories, distribution cabinets may vibrate due to the operation of production equipment. In addition, in some earthquake-prone areas, distribution cabinets also need to have a certain degree of seismic resistance to cope with the strong vibration caused by earthquakes. These complex operating environments place higher requirements on the performance and reliability of distribution cabinets, especially in terms of vibration protection. Effective measures need to be taken to ensure the normal operation of distribution cabinets.

[0003] Vibration is one of the important factors affecting the performance and reliability of high and low voltage distribution cabinets. Continuous vibration can damage the electrical components inside the distribution cabinet. For example, vibration causes poor contact of the contacts of switching devices such as circuit breakers and contactors, thereby affecting the on-off performance of the circuit. In some high-voltage distribution cabinets, vibration also causes insulation problems. For example, vibration causes wear or cracks on the surface of insulators, reducing their insulation performance, thereby increasing the risk of leakage and discharge, endangering the safety of equipment and personnel. Long-term vibration also causes loose connections of conductive components such as busbars, increases contact resistance, causes heat and even fire accidents.

[0004] Therefore, we provide a high and low voltage distribution cabinet with vibration reduction function to solve the above problems. Utility Model Content
