Technical Field

The invention relates to the field of frequency converters, in particular to a frequency converter with an explosion-proof function.

Background

The frequency converter is an electric control device which applies a frequency conversion technology and a microelectronic technology and controls an alternating current motor by changing the frequency mode of a working power supply of the motor. With the continuous improvement of the industrial automation degree, the frequency converter is also widely applied. The frequency converter is likely to explode in the using process, the explosion mainly has two reasons, most of the explosion is short-circuited outside or inside, instantaneous or long-time overvoltage and overcurrent are caused, so that the module or the capacitor is overloaded, and a heating bulge explodes; the power performance is degraded, in small numbers, due to device quality problems or natural aging. Once the frequency converter explodes, other normal equipment can be affected, and serious property loss and casualty can be caused. In the use process, environmental conditions such as dust, temperature, humidity have great influence on the fault initiation and the service life of the frequency converter. However, the existing frequency converter does not have a particularly good protection in the aspect of explosion prevention, so that a great potential safety hazard exists.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a frequency converter with an explosion-proof function, in which an explosion-proof device is arranged to improve the explosion-proof performance of the frequency converter.

In order to achieve the above and other related objects, the present invention provides a frequency converter with an explosion-proof function, which includes a cabinet body and a modular assembly disposed in the cabinet body, wherein the cabinet body includes an outer cabinet body and an inner cabinet body, both the outer cabinet body and the inner cabinet body include side plates, the outer cabinet body and the inner cabinet body share a bottom plate and a top plate, a damping device is disposed in a gap formed between the bottom plate of the outer cabinet body and the side plates of the inner cabinet body, and an explosion-proof layer is disposed on the outer surface of the inner cabinet body and the inner surface of the outer cabinet body.

Further, the modular component is arranged in the inner cabinet body.

Further, inert gas is filled in the gap.

Furthermore, the damping device is a damping box with a plurality of springs arranged inside.

Furthermore, three springs are arranged in the damping box.

Furthermore, damping device passes through the bolt and links to each other with the outer cabinet body, just damping device's thickness with the thickness in space is the same or slightly less than the thickness in space.

Further, the surface coating of the outer cabinet body has heat conduction silica gel, through heat conduction silica gel derives the inside temperature of converter fast.

Furthermore, a temperature and humidity control device is further arranged in the gap and comprises a temperature and humidity control panel, a controller is arranged on the temperature and humidity control panel, a power module, a temperature sensor and a humidity sensor are connected with the controller, and a temperature and humidity adjusting mechanism connected with the temperature and humidity control panel is arranged in the inner surface of the outer cabinet body and comprises a heater and a fan.

As described above, the frequency converter with explosion-proof function of the invention has the following beneficial effects:

1. this converter is through setting up an outer cabinet body to all coat on the outer cabinet body and the interior cabinet body and have the explosion-proof layer, thereby can provide explosion-proof characteristic.

2. Inside damping device has been increased to make the converter can provide the shock resistance, make can also keep the inside components and parts of converter can not receive too big jolting under the state of jolting, thereby further increase blast proofness.

3. Be provided with temperature and humidity control mechanism to the inside humiture of control converter that can be fine has also increased the explosion-proof of converter.
