Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
See Fig. 1 to Fig. 3, the present invention includes intelligent control unit 1 and environment control unit 2, described intelligent control unit 1 and environment control unit 2 are equipped with connection terminal and are interconnected.
Described intelligent control unit 1 comprises
Main control unit 11, carries out work for controlling described environment control unit 2, and
SPU 12, for providing the electric power supply of system,
Described environment control unit 2 comprises
Dehumidifying element 21, for condensing and isolating the moisture in power equipment 5 in air, apply on the basis of coatings at conductor, for thoroughly eliminating the phenomenon of accumulating moisture in power equipment 5 bus bar canister, present system has installed Intelligent dehumidifying unit 21 especially additional, utilizes the moisture in air to meet the principle of condensation knot, according to the requirement of moisture removal, installed some Dehumidifying elements 21 additional in relevant position, bus bar canister top, the moisture that condensation goes out discharges bus bar canister in liquid form to atomization unit 22
Atomization unit 22, for collecting isolated moisture in described Dehumidifying element 21 and moisture atomization isolation being discharged in the mode of high frequency atomization, not only ensure that the dry environment in bus bar canister, after also having stopped condensate water discharge bus bar canister, the hidden danger of accumulating or spilling on power equipment 5
Forced circulation unit 23, for air in power equipment 5 to be forced to be drawn in described environment control unit 2 and after described Dehumidifying element 21, to be discharged to becoming dry air again in power equipment 5, and
Monitoring means 24, for monitoring in real time the epidemic disaster of power equipment 5 environment, and triggers described environment control unit 2 and opens or closedown work.
Described environment control unit 2 also comprises heating arrangement 25, controls described heating arrangement 25 air heat after processing through Dehumidifying element 21 heated up by described main control unit 11.
Power equipment Intelligent dehumidifying system also comprises self-test unit 3, this self-test unit 3 is electrically connected with a fault alarm unit 4, carries out Real-Time Monitoring to judge whether sending alerting signal to described fault alarm unit 4 to the work of each parts in described environment control unit 2 by self-test unit 3.
The power equipment that present system is applicable to, as bus bridge frame, high-low pressure switch board, High-low voltage switch cabinet, ring main unit, box-type substation, dry-type transformer, instrument box etc. need automatic removing humidity, anti-condensation occasion, be particularly useful for being in the equipment that running status need drain the water away.Simultaneously this device can under strong-electromagnetic field and various severe physical environment Long-Time Service.
Now to dehumidify to crane span structure inside in detail principle of work of the present invention is described in detail:
