Abstract
The utility model discloses a heat dissipation and exhaust device for a 10KV frequency converter of a polyester heat medium furnace, which comprises a frequency converter cabinet, wherein a frequency converter, a cabinet bottom fan and a phase-shifting transformer are arranged in the frequency converter cabinet, a cabinet filter screen is arranged on a cabinet door of the frequency converter cabinet, and two cabinet top fans are arranged at the top of the frequency converter cabinet; two cabinet top fans are respectively communicated with two wall air outlets formed in the wall through air ducts, and detachable filter screen air inlets are formed in the wall. The utility model ensures that the indoor environment temperature of the frequency converter is within a reasonable range, and reduces the investment cost and the operation cost of an indoor cooling system; the self-gravity valve can prevent rainwater from entering; can dismantle filter screen air intake and avoid the indoor negative pressure that produces of converter, still can effectively prevent the entering of dust.
Description
Technical Field
The utility model relates to a polyester heat medium stove technical field especially relates to a polyester heat medium stove 10KV converter heat dissipation exhaust device.
Background
The polyester heat medium furnace device adopts 26 medium-voltage frequency converters of 10KV, the two frequency converter chambers are distributed, the frequency converters generate a large amount of heat after running, and because the frequency converters are internally provided with more electronic heating elements and heating phase-shifting transformers, the large amount of heat is discharged indoors, the indoor temperature of the frequency converters is higher, the damage is brought to the running of electrical equipment, an oversized air conditioning unit is required to cool, and the air conditioning investment cost and the air conditioning running energy consumption are both higher.
Indoor heat dissipation capacity of current converter:

Detailed Description
The following describes the embodiments of the present invention with reference to fig. 1 and 2.
A10 KV frequency converter heat dissipation and exhaust device of a polyester heat medium furnace comprises a frequency converter cabinet 6, wherein a frequency converter, a cabinet bottom fan 8 and a phase-shifting transformer 9 are installed in the frequency converter cabinet 6, a cabinet filter screen 7 is arranged on a cabinet door of the frequency converter cabinet 6, and two cabinet top fans 1 are installed at the top of the frequency converter cabinet 6; two cabinet top fans 1 are respectively communicated with two wall air outlets 3 arranged on a wall 5 through air ducts 2, and a detachable filter screen air inlet 4 is arranged on the wall 5.
And the two wall air outlets 3 are respectively provided with a self-gravity valve.
The detachable filter screen air inlets 4 are two and are respectively positioned below the two wall air outlets 3.
The air outlet of the cabinet top fan 1 is provided with the air duct 2 with equal size and is connected with the air duct 2, the air duct 2 is directly connected outdoors, the wall air outlet 3 is provided with a self-gravity valve, the self-gravity valve is automatically opened when the frequency converter operates, and the self-gravity valve is automatically closed when the frequency converter stops, so that rainwater can be prevented from entering the air outlet. Considering that the large amount of heat of the frequency converter is radiated to the outdoor to cause negative pressure in the frequency converter chamber, the detachable filter screen air inlet 4 is additionally arranged on the wall 5 of the frequency converter chamber, so that dust can be effectively prevented from entering. Indoor heat dissipation capacity after transformation:
after the transformation, the total heat productivity of the frequency converter chamber 1 is reduced by 663KW-222KW to 441 KW.
The total heating value of the improved frequency converter chamber 2 is reduced by 503KW-176KW which is 327 KW.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
