Description

Technical Field

[0001] The invention relates to the technical field of dry-type transformers, in particular to a dry-type transformer with an anti-electric shock housing. Background Art

[0002] A dry-type transformer is a transformer that does not use insulating oil, and its core and windings are not immersed in insulating oil. There are two main cooling methods for dry-type transformers: natural air cooling and forced air cooling. When cooled with natural air, the transformer can operate continuously for a long time at rated capacity, while forced air cooling can increase the output capacity of the transformer by 50%, which is suitable for intermittent overload or emergency overload operation. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, dock crane machinery and equipment, residential electricity and other places, and are used in all walks of life. Due to their high electrical strength, mechanical strength and heat resistance, dry-type transformers are particularly suitable for important places such as fire prevention, explosion prevention and moisture prevention.

[0003] Existing dry-type transformers are easily affected by faults during use and become energized. They do not have an anti-electric shock function, which makes it easy for safety accidents to occur when workers inspect the transformers. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: the dry-type transformer with an anti-electric shock shell includes a shell, a baffle is installed on the shell, and a transformer body is installed in the shell, a lifter is installed on the side of the baffle close to the transformer body, an electric controller is installed at the bottom of the lifter, a conductive rod is installed on the power input end of the electric controller, a push block is installed on the lifter, a first slide groove is opened on the upper part of the side of the baffle close to the transformer body, two moving blocks are symmetrically slidably installed in the first slide groove, the two moving blocks are respectively connected to the push blocks through push plates, and the two ends of the push plates are respectively hinged to the moving blocks and the push blocks , fixing pins are installed on the opposite back surfaces of the two moving blocks, and fixing seats are symmetrically installed on the inner two sides of the shell, and fixing holes are opened on the fixing seats. When the transformer main body leaks electricity, the current is transmitted to the electric controller through the conductive rod, so that the electric controller controls the operation of the lifter, and the lifter controls the push block to move up, so that the push block can drive the two moving blocks to move back to back in the first slide groove through the push plate during the upward movement, and the moving block can drive the fixing pin to be inserted into the fixing hole of the fixing seat, so that the baffle door on the shell can be locked and fixed, which can ensure that the baffle door will not be locked when the transformer main body is leaking electricity, thereby achieving the effect of preventing electric shock.

[0006] As a preferred technical solution, the electric controller operates when current is sensed by the conductive rod, and the electric controller is electrically connected to the lifter.

[0007] As a preferred technical solution, a reverse heat dissipation component and a heat dissipation utilization component are provided on the shell, and the operation of the lifter is used to drive the reverse heat dissipation component, and the heat dissipation utilization component is driven by the reverse heat dissipation component.

[0008] As a preferred technical solution, the reverse heat dissipation assembly includes a transmission rod, a pressing block, a driving motor, a touch switch, an electric telescopic rod, a tightening block, a rotating shaft, a driving wheel and a transmission wheel; A transmission rod is installed on the pushing block, and a pressing block is installed on the transmission rod.

A rotating shaft is rotatably installed on the upper part of one side of the shell body away from the baffle door, a driving wheel is installed at one end of the rotating shaft close to the transformer body, and a transmission wheel is installed at the other end of the rotating shaft. When the electric controller is running, the electric controller can control the driving motor to operate. At the same time, the pushing block can drive the pressing block to move upward synchronously through the transmission rod during the upward movement process, so that the pressing block can press the touch switch to control the electric telescopic rod to extend, so that the electric telescopic rod can drive the tightening block to be close to the driving wheel, so that the driving motor can control the driving wheel to rotate through the rotating shaft.

[0009] As a preferred technical solution, the reverse heat dissipation assembly further includes a fixed block, a rotating column, a rotating rod, blades, a connecting column, a driven wheel, a transmission belt and a heat dissipation hole; Two groups of fixed blocks are symmetrically installed on the upper parts of the inner two sides of the shell, and rotating columns are rotatably installed on the two groups of fixed blocks. The rotating columns on the same side are connected by a rotating rod, and a plurality of blades are installed on the rotating rod. Two connecting columns are symmetrically rotatably installed on the upper part of the shell away from the baffle door, and the connecting column on the same side is connected to the rotating column. A driven wheel is installed on the end of the connecting column close to the transmission wheel, and a transmission belt is sleeved on the two driven wheels and the transmission wheel. Two heat dissipation holes are symmetrically provided on the upper part of the shell. When the transmission wheel rotates, the transmission wheel can drive the two driven wheels to rotate through the transmission belt during the rotation process, and the driven wheel can drive the rotating rod to rotate synchronously through the connecting column and the rotating column during the rotation process, so that the rotating rod can drive the blades to rotate, so that an adsorption force is formed in the shell, so that the heat dissipation holes on the shell can inhale the cooling airflow from the outside, thereby realizing the conversion of overflow heat dissipation in the natural state of the shell into suction heat dissipation.

[0010] As a preferred technical solution, water filter membranes are installed on the two heat dissipation holes, and the cooling airflow sucked into the heat dissipation holes can be dehumidified through the water filter membranes.

When the slide plate moves downward, the slide plate can drive the linkage plate to move downward synchronously, and the linkage plate can drive the two sliders to move away from each other in the second slide groove through the push-pull plate. When the slide plate moves up, the two sliders can move towards each other in the second slide groove.

[0012] As an optimal technical solution, an embedding hole is opened on the force-bearing plate, and a ball is rolled and embedded in the embedding hole. The ball is in point contact with the outer contour of the cam. Since the ball can roll in the embedding hole, the friction between the force-bearing plate and the outer contour of the cam can be reduced.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the transformer body leaks electricity, the current is transmitted to the electric controller through the conductive rod, so that the electric controller controls the operation of the lifter, and the lifter controls the push block to move upward, so that the push block can drive the two moving blocks to move oppositely in the first slide groove through the push plate during the upward movement, and the moving block can drive the fixing pin to insert into the fixing hole of the fixing seat, so that the baffle door on the shell can be locked and fixed, which can ensure that the baffle door will not be locked when the transformer body leaks electricity, thereby achieving the effect of preventing electric shock.

[0014] The reverse heat dissipation component set up in the present application can enable the driving motor to control the driving wheel to rotate through the rotating shaft, so that the rotating rod can drive the blades to rotate in the shell, so that an adsorption force is formed in the shell, so that the heat dissipation holes on the shell can absorb the external cooling airflow, thereby realizing the conversion of the overflow heat dissipation of the shell in the natural state into suction heat dissipation.
