Problems solved by technology
[0003] The existing distribution box is limited in volume, so the heat dissipation holes are small, and an external heat dissipation device is required for heat dissipation, and the shock resistance is poor. During transportation, the components inside the distribution box will be damaged. Therefore, an adjustable heat dissipation slot is designed. And the distribution box with good anti-seismic performance is worth considering

Description
technical field [0001] The invention relates to the field of power supply equipment, in particular to a power distribution box with adjustable heat sink size. Background technique [0002] The distribution box is a general circuit distribution box for all users to use electricity. The distribution box is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Constitutes a low-voltage power distribution device. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal w...
