[0005] The purpose of the present invention is to solve the need to maintain the inverter when it is used, including dust removal on the upper and lower vents of the inverter. Since the inverter will generate heat during use, dust will be concentrated on the upper and lower vents. Timely cleaning will affect the use of frequency converters, and a safety protection device for frequency converters and its protection methods are proposed

Embodiment 1
[0041] refer to Figure 1-8, a frequency converter safety protection device, including a frequency converter part 1 with a built-in cooling fan, when the cooling fan works to dissipate heat, it can drive the gas flow in the frequency converter part 1, and the frequency converter part 1 is provided with an upper vent 102 and a lower vent. 101, specifically, the upper vent 102 is used for gas entry, and the lower vent 101 is used for gas discharge, and further includes:
[0042] The sliding frame 2 is slidably connected to the upper ventilation port 102, and the sliding frame 2 is fixedly connected with a lower dustproof net 201 matching the upper ventilation port 102. filter dust;
[0043] One end of the dust-proof spring 204 is fixedly connected to the sliding frame 2, and the other end is attached to the sliding frame 2, that is, the sliding frame 2 is not attached to the dust-proof spring 204. When the sliding frame 2 moves up, it can contact the dust-proof spring 204. Sep...
Embodiment 2
[0058] refer to Figure 1-8 , an inverter safety protection method, which mainly includes the following steps:
[0059] S1. The air in the frequency converter 1 is driven to flow by the cooling fan in the frequency converter 1, so that the gas enters from the upper vent 102 and is discharged through the lower vent 101 and the ventilation pipe 104;
[0060] S2. When the gas passes through the ventilation pipe 104, it is acted by the shunt component, so that the gas first enters the piston groove 3001, so that the gas pressure in the piston groove 3001 increases and then flows out from the ventilation pipe 104: in the lower ventilation port 101, there are When the gas is discharged, the gas in the lower vent 101 will first enter the piston groove 3001 through the ventilation pipe 104. When the gas pressure in the piston groove 3001 reaches the maximum, the gas cannot enter the piston groove 3001, so that the gas squeezes and rotates the sealing plate. 105 is rotated, the U-shap...

Abstract
The invention discloses a frequency converter safety protection device and a protection method thereof, belonging to the field of frequency converters. A safety protection device for a frequency converter, including a frequency converter device with a built-in cooling fan, the frequency converter device is provided with an upper vent and a lower vent, and is characterized in that it also includes: a sliding frame slidably connected to the upper vent , the sliding frame is fixedly connected with a lower dust-proof net that matches the upper vent; the dust-proof spring is fixedly connected to the sliding frame at one end and attached to the sliding frame at the other end; the limit member is up and down There are two groups, which are used to limit the up and down sliding of the sliding frame; the scraping frame that is slidably connected to the frequency converter; the present invention can control the gas entering the frequency converter through the upper dust-proof net and the lower dust-proof net. The dust is filtered, and the dust on the lower dust-proof net can be cleaned, and the cleaning operation can be realized reciprocally, the replacement frequency of the lower dust-proof net is low, and the dust removal effect is good.
Description
technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter safety protection device and a protection method thereof. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply; [0003] The inverter is mainly composed of rectifier, filter, inverter, braking unit, drive unit, detection unit and micro-processing unit. The required power supply voltage can achieve the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions, such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of industrial automation, the inverter has also been widely used; [0004] When the inverter is in use, it needs to be maintained, including dust removal from the upper ...
