Abstract
The invention discloses fan part heating equipment, which comprises a temperature sensor, a controller, a control relay, heating elements, a power supply, a power voltage stabilizer, a frequency conversion unit and a heating heat-preserving control cabinet, wherein the controller, the control relay, the power supply, the power voltage stabilizer and the frequency conversion unit are respectively arranged in the heating heat-preserving control cabinet. The fan part heating equipment has the advantages that all heating elements are heated by using the controller, and fan parts can be heated; and under the condition that the self extreme-low-temperature operation stability is kept, normal operation of a fan at the lowest working temperature can be ensured.
Description
Technical field
The present invention relates to a kind of firing equipment, the fan part that is primarily aimed under the cryogenic conditions can normally move, and the fan part firing equipment under a kind of condition of ultralow temperature of design.
Technical background
Present stage wind-power electricity generation and sun power obtained develop rapidly in China; But the control system overwhelming majority relies on import; And most of blower fan control systems are work under the normal temperature weather conditions, and this is not suitable for the cold snap of northern China with regard to making most of blower fan control system of introducing, particularly when temperature below-30 ℃ the time; Normal operation is difficulty, has had a strong impact on blower fan applying at northern area.CN201060398Y discloses the fan part independence heating arrangement under a kind of cryogenic conditions, but this operational effect under the condition of utmost point low temperature of this device is not good, and the fluctuation of electric current is bigger to the heats influence.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective; And a kind of fan part firing equipment is provided; It can guarantee under the situation that does not change former blower fan normal temperature control system, the blower fan critical piece to be heated, and can also guarantee the stability that himself is worked simultaneously under utmost point low temperature.
Technical scheme of the present invention is following:
A kind of fan part firing equipment; Be used for that the parts to blower fan add heat control under utmost point low temperature; It comprises temperature sensor, controller, pilot relay, heating element, power supply, power regulator and converter unit; Said temperature sensor is used for the temperature acquisition of said fan part and transmits signal to said controller; Said controller is used for controlling according to the signal of temperature sensor the break-make of heating element and pilot relay; Said pilot relay is used to receive the control signal of said controller and said heating element is regulated; The signal that said heating element receives said controller and pilot relay is used for the parts to blower fan are heated, and said power supply is in order to give said controller, pilot relay, voltage stabilizer, converter unit and heating element power supply, and said power regulator and converter unit are in order to control said power supply respectively; This fan part firing equipment also comprises the heat tracing switch board, and said controller, pilot relay, power supply, power regulator and converter unit all are installed in the said heat tracing switch board.
Said heat tracing switch board adopts the asbestos adiabator plate to constitute.
Described heating element is an electrical bar.
Power supply, promptly power supply is an AC power, and voltage stabilizer and converter unit are installed.Power supply is supplied power separately in the blower fan control system of outside.
This fan part firing equipment is arranged separately in the heating control cabinet, adopts the asbestos insulation board insulation around the switch board.
The invention has the beneficial effects as follows: the fan part firing equipment of the present invention's design heats each heating element through controller; Can heat fan part again simultaneously; Under the condition of maintenance self utmost point cold operation stability; It not only can guarantee the normal operation of blower fan under minimum operating temperature (30 ℃) condition, but also can under minimum blower fan limit existence temperature (40 ℃) condition, not damage blower fan normal temperature control system; Also have practicality simple to operate, characteristics such as applied range simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
It in the accompanying drawing 1 a kind of fan part independence firing equipment of the present invention; The parts that it is mainly used in blower fan are carried out at the heat control that adds beyond the blower fan control system; Most of parts of this fan part independence firing equipment (like controller, pilot relay, power supply, power regulator and converter unit etc.) are installed in the heating control cabinet (not shown); Temperature sensor 1, pilot relay 3 and heating element that this firing equipment mainly comprises controller 2, links to each other with controller respectively; This pilot relay also links to each other with heating element; Voltage stabilizer that links to each other with power supply and converter unit, and the power supply of giving controller, pilot relay and heating element power supply respectively, wherein:
Temperature sensor is used for the temperature of collection site fan part, and the value of output temperature is given controller then;
Controller is used to control the break-make of heating element and pilot relay, and it is to export to heating element and pilot relay switching on and off with decision pilot relay and heating element according to the detected temperature of temperature sensor as signal;
Pilot relay is used for power supply and protection heating element, and it receives the control signal of self-controller, outputs signal to heating element then;
Heating element is used for the parts heating to the blower fan control system of outside;
Power supply; Be used for to controller, pilot relay, voltage stabilizer, converter unit and heating element power supply; The 380V alternating current is adopted in the power supply design; The voltage stabilizer of its installation and converter unit are further stablized the heats of heating element, and this power supply is independent of outside blower fan control system and supplies power separately.
In the present embodiment, the critical piece of this fan part firing equipment adopts and is placed on separately in the heating control cabinet, and design adopts the asbestos adiabator plate to be incubated around the switch board, guarantees under ultralow temperature, can normally move.
Unaccounted and the existing technology of other that the present invention relates to is consistent.
