Description

Technical Field

[0001] This utility model relates to the field of programmable power supply technology, and more specifically, to an industrial programmable power supply device. Background Technology

[0002] A programmable power supply (PPS) is a power supply device that can adjust the output voltage and current through external control signals or internal preset programs. It is commonly used in laboratories, production line testing, research and development, and other applications that require precise control of power parameters. However, PPS used in industry generate a lot of heat due to the large number of loads and high voltage and current requirements of industrial equipment.

[0003] Current programmable power supply devices use a stacked installation method for power converters that are prone to generating heat. This reduces the heat dissipation area of ​​the power converter, preventing the heat from being dissipated in time. As operating time accumulates, a large amount of heat can easily cause the power converter to overheat and overload, which can lead to power converter failure and affect the normal use of the programmable power supply device.

The programmable control cabinet has a control circuit fixedly installed inside, including a microprocessor and a feedback circuit. The programmable control cabinet is provided with GPIB, USB, LAN, and RS-232 interfaces for connecting to external devices. The power cabinet has a power conversion cavity inside, and at least one support plate is installed inside the power conversion cavity. The front and back of the support plate are fixedly connected to the power cabinet by bolts. Each support plate includes two mounting plates, and uniformly distributed connecting support strips are integrally formed between corresponding front and rear mounting plates. The connecting support strips form a rectangular array, and the inner gaps of the array form ventilation chambers. A power converter is placed above each support plate, and the power converter is electrically connected to the control circuit.

[0012] The power cabinet has strip-shaped mounting slots on both the front and back sides. The mounting plate is fixed to the power cabinet by bolts inserted into the inside of the strip-shaped mounting slots.

[0013] As a further description of the above technical solution:

[0014] The programmable control cabinet has a display screen for displaying power status information and a control panel for setting and adjusting power parameters fixedly installed on its front.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] In this solution, when the power converter is working, the working heat of the power converter can be easily ventilated and dissipated through the gaps between the connecting support bars due to the support plate supporting the power converter and separating adjacent power converters.

A control circuit 5 is fixedly installed inside the programmable control cabinet 2. The control circuit 5 includes a microprocessor and a feedback circuit. The programmable control cabinet 2 is provided with GPIB, USB, LAN and RS-232 interfaces for connecting to external devices. A power conversion cavity 3 is provided inside the power conversion cavity 3. At least one support plate 4 is provided inside the power conversion cavity 3. The front and back of the support plate 4 are fixedly connected to the power cabinet 1 by bolts. The support plate 4 includes two mounting plates 41. A uniformly distributed connecting support strip 42 is integrally formed between the two corresponding mounting plates 41. The connecting support strip 42 forms a rectangular array, and the gaps on the inner side of the array form a ventilation cavity 43. A power converter 6 is placed above each support plate 4. The power converter 6 is electrically connected to the control circuit 5.

[0026] In this invention, a suitable number of support plates 4 are installed according to the industrial equipment requirements to be loaded by the programmable power supply, and fixed by mounting plates 41, so as to install a corresponding number of power converters 6 inside the power supply cabinet 1. After the power converters 6, which are responsible for converting the input AC or DC power into the required output voltage and current, are placed on the support plates 4, they can be easily connected to external computers, programmable controllers and other devices through GPIB, USB, LAN and RS-232 interfaces, so as to facilitate programming control of the control circuit 5 in the programmable control cabinet 2 to adjust the working state of the power converters 6. When the power converters 6 are working, due to the support of the support plates 4 for the power converters 6 and the separation of adjacent power converters 6, the working heat of the power converters 6 can be easily ventilated and dissipated through the gaps between the connecting support bars 42. At the same time, the contact between the connecting support bars 42 and the support of the power converters 6 can directly conduct heat and expand the heat dissipation area to a certain extent, thereby improving the heat dissipation efficiency and ensuring the working stability and service life of the programmable power supply device.

[0029] Please see Figure 4 The mounting plate 41 has a ventilation opening 411 that communicates with the ventilation cavity 43, and a ventilation fan 412 located inside the ventilation opening 41 is fixedly installed on the mounting plate 41.

[0030] In this invention, the ventilation opening 411 facilitates communication between the outside and the ventilation cavity 43, thereby promoting airflow. When the ventilation fan 412 is powered on, it can further improve the airflow effect and enhance the heat dissipation.

[0031] Please see Figure 1 In this case, the power cabinet 1 has strip-shaped mounting grooves 7 on both the front and back sides. The mounting plate 41 is fixed to the power cabinet 1 after being inserted into the strip-shaped mounting grooves 7 by bolts.

[0032] In this utility model, the mounting plate 41 and the power cabinet 1 can be easily adjusted by the strip mounting groove 7, so that the installation height can be adjusted according to the thickness of the power converter 6 and the number of power converters 6 to be installed, thereby meeting the installation requirements.
