Background technology
High-low voltage electric power distribution cabinet be exactly as its name suggests in power supply system for carrying out electric energy distribution, control, measure and
The controller switching equipment of connection cables, general power supply administration, electric substation are all to use high-tension switch cabinet, are then drawn through transformer pressure-reducing low-pressure side
Go out to low-voltage distribution cabinet, low-voltage distribution cabinet in the distribution board to each electricity consumption, control cabinet, switch-box, the inside is exactly by by one
A little switch, breaker, fuse, button, indicator lamp, instrument, electric wires etc protection device are assembled integrally and reach design function
It is required that power distribution equipment equipment.
The electric elements module and various discrete electronic devices of more much caloric values are generally integrated inside power distribution cabinet, these
Electric elements work in hot environment for a long time, not only can premature aging, reduction of service life, and, once inside power distribution cabinet
Temperature is too high, will have a strong impact on control accuracy and control stability, even results in electric elements and burns, and causes accident.It is existing
The measure taken is：In peak of power consumption period, chamber door is opened, lowered the temperature with electric fan or installation cabinet fan, this side
Formula is easily brought in regulator cubicle the foreign matters such as dust, chip into, causes short circuit, and have some heater element fans close to the inner portion to blow
Less than, do not allow very much easy heat radiation, weak heat-dissipating will result in element overload and burn, and because power distribution cabinet is because powered and modeling
Materials and parts are relatively more, so once burning, it is easy to as circuit spreads, cause larger economic loss.In addition, turning in power distribution cabinet
Driving is needed to be sling by the suspension ring at the top of power distribution cabinet during shifting, it is mobile；But because power distribution cabinet height is higher, it is necessary to people
By ladder or its instrument, he climbs to power distribution cabinet top, and the suspension hook of driving is caught on into suspension ring, so can undoubtedly be brought to transfer
Many troubles, there is the potential safety hazard dropped in the people of power distribution cabinet top operational.
