Description

Technical Field

[0001] The utility model relates to the technical field of industrial rectifier cabinets, in particular to a cooling water exhaust system for a rectifier cabinet device and a rectifier cabinet device. Background Art

[0002] Since the rectifier cabinet is a device that converts AC550v into DC750v, and the thyristors on the device are installed at the incoming three-phase AC 550v. A large amount of heat will be generated during operation. The cooling method adopted by equipment manufacturers is to pass cooling water through the equipment to achieve the effect of cooling the thyristors. Normally, the temperature is maintained at about 50°C. However, when there are a large number of bubbles in the cooling water, a good cooling effect cannot be achieved. When the thyristor temperature is as high as 100°C for a long time, there will be risks such as the water pipe melting and falling off, the internal part of the equipment short-circuiting and exploding due to water ingress, and the thyristor exploding due to high temperature. To avoid the equipment from stopping running due to such problems, it is extremely urgent and necessary to solve the problem of how to eliminate the bubbles in the cooling water. Content of the Utility Model

[0003] The utility model provides a cooling water exhaust system for a rectifier cabinet device and a rectifier cabinet device, which can solve the problem that the cooling effect cannot be guaranteed due to a large number of bubbles in the cooling water circulation process of the existing rectifier cabinet device.

[0004] To achieve the above object, in the first aspect, the utility model provides the following technical solution: A cooling water exhaust system for a rectifier cabinet device, including a three-way connector. The first port of the three-way connector is used to communicate with the water outlet of the cooling water of the thyristor device in the rectifier cabinet. The second port of the three-way connector is used to communicate with the water return port of the cooling water of the thyristor device in the rectifier cabinet. The third port of the three-way connector is communicated with an exhaust valve. The exhaust valve is arranged at the upper part of the three-way connector and can be connected to the existing cooling water circulation system of the rectifier cabinet device. When the cooling water flows through the three-way connector, the air in the cooling water will move upward and be discharged smoothly from the exhaust valve, so as to achieve the purpose of separating the cooling water from the air, reducing the failures such as the thyristor temperature being too high to dissipate heat in time, resulting in the hose being scorched and falling off, and the rectifier cabinet short-circuiting and exploding due to water ingress, and ensuring the normal operation of the rectifier cabinet.

[0005] Preferably, the first port and the second port of the three-way connector are axially opposite to each other. The third port is arranged at a position between the first port and the second port, and the axis of the third port is perpendicular to the axes of the first port and the second port. The axially opposite arrangement of the first port and the second port allows the cooling water to pass through smoothly, and the air can move upward smoothly to the third port when flowing through.

[0006] Preferably, an inlet connection pipe is installed on the first through port of the three-way connector, and an outlet connection pipe is installed on the second through port of the three-way connector, which is convenient for connecting with external pipelines.

[0007] Preferably, the inlet connection pipe is connected to the outlet of the thyristor equipment cooling water in the rectification cabinet through an inlet hose, and the outlet connection pipe is connected to the return port of the thyristor equipment cooling water in the rectification cabinet through an outlet hose. The inlet hose and the outlet hose can improve the installation flexibility of the cooling water exhaust system and enhance the versatility.

[0008] Preferably, the third through port is connected to an exhaust valve through a connecting assembly, making the connection between the exhaust valve and the third through port more flexible and facilitating the disassembly and replacement of the exhaust valve.

[0009] Preferably, the connecting assembly includes a lower connecting pipe, an upper connecting pipe, and a union nut for connecting the lower connecting pipe and the upper connecting pipe. The lower connecting pipe is connected to the third through port, and the upper end of the upper connecting pipe is connected to the exhaust valve.

[0010] Preferably, the exhaust valve is an adjustable exhaust valve, and the opening degree of the exhaust switch can be adjusted by observing the actual operation effect to achieve the purpose of separating the cooling water of the equipment from the air.

[0011] In a second aspect, the present invention further includes a rectification cabinet device, which includes the cooling water exhaust system described in the first aspect. Among them, the cooling water exhaust system is vertically installed in the rectification cabinet device.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The structure is simple and reliable, and it can be connected to the existing cooling water circulation system of the rectification cabinet device. When the cooling water flows through the three-way connector, the air in the cooling water will move upward and be smoothly discharged from the exhaust valve, so as to achieve the purpose of separating the cooling water from the air, reducing failures such as the thyristor temperature being too high to dissipate heat in time, resulting in the hose burning and falling off, and the rectification cabinet being short-circuited and exploded due to excessive air in the cooling water system, and ensuring the normal operation of the rectification cabinet.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The present invention aims to solve the problem that in the cooling water circulation process of existing rectifier cabinet equipment, a large number of bubbles exist, resulting in the inability to guarantee the cooling effect. As Figure 1-2 shown, the following technical solutions are provided: A cooling water exhaust system for a rectifier cabinet equipment, including a three-way connector 5. The first port of the three-way connector 5 is used to communicate with the water outlet of the thyristor equipment cooling water in the rectifier cabinet. The second port of the three-way connector 5 is used to communicate with the water return port of the thyristor equipment cooling water in the rectifier cabinet. The third port of the three-way connector 5 is connected to the exhaust valve 1. The exhaust valve 1 is arranged above the three-way connector 5 and can be connected to the existing cooling water circulation system of the rectifier cabinet equipment. When the cooling water flows through the three-way connector 5, the air in the cooling water will move upward and be smoothly discharged from the exhaust valve 1, so as to achieve the purpose of separating the cooling water from the air, reducing faults such as the thyristor temperature being too high to dissipate heat in time, resulting in the hose being scorched and falling off, and the water inlet in the rectifier cabinet being short-circuited and exploded due to too much air in the cooling water system, and ensuring the normal operation of the rectifier cabinet.

[0020] Specifically, the three-way connector 5 can adopt a commonly used T-shaped three-way joint on the market at present, that is, the first port and the second port of the three-way connector 5 are axially opposite to each other. The third port is arranged at a position between the first port and the second port, and the axis of the third port is perpendicular to the axes of the first port and the second port. The axially opposite arrangement of the first port and the second port allows the cooling water to pass through smoothly. When installing, the first port and the second port are installed horizontally, so that the air in the cooling water flowing through the first port and the second port is located above the three-way connector 5, so that the air can smoothly move upward to the third port and be discharged from the exhaust valve 1.

[0021] In actual application, the positions of the first port, the second port and the third port can be adjusted according to needs, as long as it is ensured that the third port is located at the uppermost end.

[0022] The exhaust valve 1 can select a common model on the market, such as an automatic exhaust valve with the model E121-R, or an adjustable exhaust valve can be adopted. By observing the actual operation effect, the opening degree of the exhaust switch can be adjusted to achieve the purpose of separating the cooling water of the equipment from the air.

[0023] For the convenience of accessing the existing rectifier cabinet, a water inlet connecting pipe 6 is installed on the first through port of the three-way connector 5, and a water outlet connecting pipe 7 is installed on the second through port of the three-way connector 5, which is convenient for connecting with external pipelines.

[0024] Meanwhile, as Figure 2 shown, the water inlet connecting pipe 6 is connected to the water outlet of the cooling water of the thyristor device in the rectifier cabinet through a water inlet hose 8, and the water outlet connecting pipe 7 is connected to the water return port of the cooling water of the thyristor device in the rectifier cabinet through a water outlet hose 9. The installation flexibility of the cooling water exhaust system can be improved through the water inlet hose 8 and the water outlet hose 9, and the versatility can be enhanced.

[0025] In this embodiment, as Figure 1 shown, the third through port is connected to the exhaust valve 1 through a connecting assembly, making the connection between the exhaust valve 1 and the third through port more flexible and facilitating the disassembly and replacement of the exhaust valve 1. Specifically, the connecting assembly may include a lower connecting pipe 4, an upper connecting pipe 2, and a union nut 3 for connecting the lower connecting pipe 4 and the upper connecting pipe 2. The lower connecting pipe 4 is connected to the third through port, and the upper end of the upper connecting pipe 2 is connected to the exhaust valve 1.

[0026] In this embodiment, there is also provided a rectifier cabinet device, which includes the above-mentioned cooling water exhaust system. Among them, the cooling water exhaust system is vertically installed in the rectifier cabinet device, and the vertical placement is conducive to discharging the air in the cooling water.

If the specific posture changes, the directional indications will also change accordingly.

[0028] In addition, in the present invention, descriptions such as "primary" and "secondary" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "primary" and "secondary" may explicitly or implicitly include at least one such feature.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.
