Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transformer rectifiers, and more specifically, particularly relates to a transformer rectifier for the transformer industry. Background Art
[0002] The rectifier transformer is the power transformer of the rectifier equipment. The characteristic of the rectifier equipment is that the primary side inputs AC, and the secondary side outputs DC after passing through the rectifier element. Current conversion is the general term for the three working modes of rectification, reverse current and frequency conversion. Rectification is the most widely used one among them. The transformer used as the power supply of the rectifier device is called a rectifier transformer.
[0003] In order to improve the heat dissipation efficiency, some current transformer rectifiers accelerate the air flow speed inside the transformer rectifier by adding a cooling fan. However, when the internal components of the transformer rectifier short-circuit and catch fire, the fast-flowing air will accelerate the burning speed of the fire, causing the internal components of the transformer rectifier to be quickly burned, resulting in serious economic losses.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a transformer rectifier for transformer industry is provided, in order to achieve the purpose of having more practical value. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a transformer rectifier for transformer industry, which is achieved by the following specific technical means:
[0006] The heat dissipation fan of the present invention is connected with the air filter screen of the present invention, and the heat dissipation fan has the shape of a circle, and the shape of the circle is connected with the air filter screen of the present invention.
[0007] Furthermore, one end of the rotating rod passes through one side of one group of the power chambers and a motor is installed thereon.
[0008] Furthermore, a sensor is installed on the top of the machine body, and the sensor is electrically connected to the electric jet head and the motor through a wire.
[0009] Furthermore, a protective net is installed on one side of the heat dissipation fan.
[0010] Furthermore, a gas injection port is provided on the top of the gas storage box.
[0011] Furthermore, the driving bevel gear is meshed with the driven bevel gear.
[0012] Furthermore, the gas in the gas storage box is heptafluoropropane.
[0013] Furthermore, heat sinks are installed on the other two sides of the machine body.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] By using the cooling fan in conjunction with the filter, start the cooling fan, which can quickly discharge the hot air inside the machine body. When the external low-temperature air enters the machine body, the dust and impurities in the air can be filtered out through the filter, thereby improving the heat dissipation effect of the machine body.
[0016] Through the coordinated use of the motor, rotating rod, active bevel gear, driven bevel gear, rotating shaft, lead screw, baffle, sensor and electric jet head, when a fire occurs inside the machine body, the sensor will be triggered, and the sensor will send a start command to the motor. The motor drives the rotating rod to rotate, and the rotating rod drives a pair of active bevel gears to rotate. The active bevel gear drives the rotating shaft to rotate through the driven bevel gear, and the rotating shaft drives the lead screw to rotate. The lead screw rotates in the threaded groove to move the baffle upward, so that a pair of baffles can block the air inlet and the heat dissipation port respectively, prevent air flow, and slow down the spread of the fire. At the same time, the sensor will send an opening command to the electric jet head. When the electric jet head is opened, the heptafluoropropane gas in the gas storage box will be sprayed into the inside of the machine body, thereby achieving the effect of rapid fire extinguishing, thereby reducing damage to the inside of the machine body and reducing economic losses.
