Description

Built-in surge protector of low-voltage power distribution cabinet Technical Field The utility model relates to the technical field of low-voltage power distribution cabinets, in particular to a built-in surge protector of a low-voltage power distribution cabinet. Background In the operation structure of the modern power system, the key and irreplaceable functions are played, the key and irreplaceable functions are used as a core hub for power distribution and control, electric energy from an upper power supply is received and reasonably distributed, and stable and reliable power supply is provided for a plurality of low-voltage electric equipment. The current surge protector is when in actual use, usually use the fastener to carry out mechanical fixation, perhaps adopt direct bonding's technology, along with the continuous accumulation of equipment live duration, adopt the fixed surge protector of fastener, at the switch board daily operation in-process, can produce continuous vibration, this kind of vibration comes from the operation of inside electrical equipment, make the fastener become flexible gradually, frictional force between the screw thread reduces, lead to connecting no longer inseparable, finally lead to the fastener to drop, adopt direct bonding mode to fix, glue can age gradually, reduce its adhesive strength, in case the fastener is not hard up to drop or the circumstances that adhesive strength reduces appear, the surge protector just probably drops from the mounted position. Disclosure of utility model The utility model aims to provide a built-in surge protector of a low-voltage power distribution cabinet so as to solve the problems in the background technology.
