Abstract
The utility model discloses a high-voltage frequency conversion device capable of overheating protection. The device comprises a body, which is provided with a bypass cabinet, a transformer cabinet, a power cabinet and a control cabinet, wherein the bypass cabinet and the transformer cabinet are respectively connected with the power cabinet, the power cabinet is connected with the control cabinet, and a temperature-detecting device is arranged in the body. The device is provided with the temperature-detecting device, thus the overheating protection can be carried out to the device, especially to main heating components, so that the device can be guaranteed to be away from burnout or accelerated aging, reduce the occurrence of faults, prolong the service lifetime, and reduce maintenance cost.
Description
Technical field
The utility model relates to a kind of converter plant, specifically high voltage frequency converter.
Background technology
Converter plant VFD (Variable-frequency Drive) uses converter technique and microelectric technique, and the frequency by changing the machine operation power supply and the mode of amplitude are controlled the Electric Drive element of alternating current motor.Converter plant is integrated high-voltage high-power transistor technology and electron controls technology are used widely.The effect of converter plant is frequency and the amplitude that changes the alternating current machine power supply, thereby changes the cycle of its moving magnetic field, reaches the purpose of level and smooth control motor speed.The appearance of converter plant, make complicated speed regulating control oversimplify, with converter plant+mouse cage AC formula induction motor combination replacement the most of work that originally can only finish with direct current machine, dwindled volume, reduced maintenance rate, made drive technology develop into the new stage.Present high voltage frequency converter does not generally have the device of overtemperature protection; equipment is easy to generate excessive temperature when work like this; each parts of equipment at high temperature operate easy accelerated ageing for a long time and produce fault; thereby reduced equipment useful life, increased maintenance cost, also influence production work easily.
The utility model content
For overcoming the deficiencies in the prior art,, the utility model can carry out the high voltage frequency converter that overtemperature protection prolongs service life of equipment thereby providing a kind of.
For achieving the above object; but technical solution adopted in the utility model is a kind of high voltage frequency converter of overtemperature protection; comprise body; in body, be provided with bypass cabinet, transformer case, power cabinet and control cubicle; wherein bypass cabinet and transformer case join with power cabinet respectively; power cabinet and control cubicle join, and are provided with temperature-detecting device in described body.
In order to make main heater element obtain better overtemperature protection, be provided with transformer in the described transformer case, be provided with power cell in the described power cabinet, described transformer and power cell all join with temperature-detecting device.
Beneficial effect: the utility model is owing to installed temperature-detecting device in equipment; can carry out overtemperature protection to the equipment components and parts that particularly mainly generate heat; can guarantee like this that equipment can not cause and burn or accelerated ageing; reduced the generation of fault; prolong the useful life of equipment, reduced maintenance cost.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, present embodiment is being to implement under the prerequisite with technical solutions of the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model.
As shown in Figure 1; but a kind of high voltage frequency converter of overtemperature protection; comprise body 1; in body 1, be provided with bypass cabinet 2, transformer case 3, power cabinet 4, control cubicle 5 and temperature-detecting device 6; wherein bypass cabinet 2 and transformer case 3 join with power cabinet 4 respectively, and power cabinet 4 joins with control cubicle 5, is provided with transformer 7 in transformer case 3; in power cabinet 4, be provided with power cell 8, and transformer 7 and power cell 8 join with temperature-detecting device 6 all.
Operation principle: at first temperature-detecting device is carried out temperature and preset, the transformer limiting temperature is set to 145 ℃, the limiting temperature of power cell is made as 75 ℃, when the in a single day detected in the course of the work components and parts ambient temperature of equipment surpasses preset value like this, temperature-detecting device will be reported to the police and detected components and parts are quit work automatically, make operating personnel in time find situation and handle, prolonged greatly equipment useful life, reduced the rate of breakdown of equipment.
