Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinet equipment, in particular to a ring network cabinet device. Background Art

[0002] A ring main unit is an electrical device that is a group of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled interval ring main unit. Its core part uses load switches, fuses, circuit breakers, etc. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety.

[0003] The authorized patent of my country with patent number "201720647252.2" and patent name "A heat dissipation ring network cabinet door" records that "when the blower fan is turned on, the air outside the cabinet will be blown into the inside of the ring network cabinet, and the air guide plate will allow the air to flow toward the bottom of the ring network cabinet. When the exhaust fan is turned on, the air in the cabinet will be drawn out of the outside of the ring network cabinet, thereby forming a rapid air flow inside the ring network cabinet, taking away the heat dissipated by the electrical components in the ring network cabinet, and preventing the electrical components from overheating." As can be seen from the above, although the comparative patent has achieved a better heat dissipation effect to a certain extent, it is limited by the structure. Like other existing technologies in this field, there are more or less some technical problems, which are specifically manifested as follows. First: the heat dissipation method is achieved through a blower and an exhaust fan. In this way, due to the single heat dissipation through air, the heat dissipation effect is relatively poor; and because it is impossible to achieve sealing in order to ensure the inflow and outflow of air, excessive external dust and the like enter the cabinet, which will have an adverse effect on the working performance of the internal electrical components. Second: When the status of the corresponding electrical control equipment in the cabinet changes (for example, in the existing technical application of remote control of electrical equipment, after the staff issues the corresponding electrical equipment opening or closing command at the remote end, they cannot get the operation feedback, and therefore cannot guarantee the effective control of the electrical equipment), or when the cabinet door is not closed properly, the relevant management personnel cannot understand the specific situation if they do not go to the site. This not only cannot guarantee safe power supply, but also poses certain safety hazards (for example, the cabinet door is not closed properly, someone accidentally touches the internal electrical equipment and gets an electric shock, or small animals enter the cabinet and touch the electrical equipment, causing the electrical equipment in the cabinet to work abnormally). Utility Model Content

[0004] In order to overcome the drawbacks of the existing ring main unit due to structural limitations as described in the background, the utility model provides a ring main unit device based on the ring main unit body, which cools the electrical equipment in the cabinet by water cooling, and can relatively achieve a better cooling effect. When the corresponding electrical equipment in the cabinet is opened and closed, and when any cabinet door is not closed properly, the remote relevant personnel can be prompted by text message at the first time, thereby ensuring that the staff can effectively remotely control the relevant electrical equipment and achieve a better safety effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A ring network cabinet device, comprising a ring network cabinet body, a one-way air valve, a short message module, a magnet, a liquid pump, a cooling fan, a heat pipe, and a reed switch; characterized in that the outer side of the shell of the ring network cabinet body is a hollow two-layer structure, and the air inlet pipe of the one-way air valve is installed on one side of the upper end of the shell; a water adding pipe is installed on the other side of the upper end of the shell, and water is added between the inner and outer layers of the outer side of the shell; branch pipes are installed on the rear two sides of the shell respectively, and the liquid pump is installed on the rear side of the ring network cabinet body, one end of one branch pipe is installed together with one end of the heat pipe, the other end of the heat pipe is installed together with the water outlet pipe of the liquid pump, the water inlet pipe of the liquid pump and one end of the other branch pipe are installed together, and the cooling fan is installed at the rear outer side end of the heat pipe; the magnet is installed at the front end of the load switch operating handle of the ring network cabinet body, there are at least two reed switches, and the two reed switches are respectively installed at the upper and lower ends of the operating handle; the short message module is installed in the ring network cabinet body, and the reed switch is electrically connected to the signal input end of the short message module.

[0007] Furthermore, the reed switch is a normally open contact type glass shell reed switch.

[0008] Furthermore, the shell material of the ring main unit body is stainless steel.

[0009] Furthermore, when the load switch is closed, the magnet approaches a reed switch at the upper end, and the moving contact and the static contact inside the reed switch are connected. When the load switch is open, the magnet approaches a reed switch at the lower end, and the moving contact and the static contact inside the reed switch are connected.

[0010] The beneficial effects of the utility model are as follows: the utility model is based on the ring main unit and has all the functions of all ordinary ring main units. The utility model dissipates heat through a water cooling cycle, which has a better heat dissipation effect than single air heat dissipation, and prevents external dust from entering the cabinet and causing adverse effects on the operation of electrical equipment (such as affecting heat dissipation, causing dirty contacts of electrical equipment and poor contact, etc.); in application, after the staff remotely controls the load switch to open or close, or the cabinet door is not closed properly, the SMS module will automatically push a corresponding SMS to the mobile phone of the remote staff, so that the staff can immediately understand whether the remote control is successful and the cabinet door is not closed properly, and timely make targeted disposal to ensure safe and stable power supply. Based on the above, the utility model has a good application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

The upper and lower ends of the front part of the switch 6 (outside the front door of the ring main unit body); there are three power switches, and the front right side of the cabinet body of the ring main unit shell has three grooves at a certain distance from top to bottom. The three power switches S1, S2, and S3 are respectively insulated and installed in the three grooves, and the buttons of the power switches S1, S2, and S3 face forward; the power module A1 and the SMS module A2 are installed on the circuit board in the component box 7, and the component box 7 is installed at the lower end of the ring main unit body 1. After the cooling fan 9 is installed in place, it is about 30 cm away from the front end of the wall (to facilitate air circulation).

The power switches S1, S2, and S3 are normally closed contact type power switches with inching buttons. The shell material of the ring network cabinet body 1 is stainless steel. When the load switch 6 is closed and the operating handle 6 is upward, the upper magnet 3 and a reed switch GH1 at the upper end are close, and the moving contact and the static contact inside the reed switch GH1 are connected.

[0017] Figure 1 , 2As shown in Figures 3 and 4, the present invention uses water cooling to dissipate heat, which has the advantage of good heat dissipation effect compared with the existing air cooling method, and prevents external dust from entering the cabinet and causing adverse effects on the operation of electrical equipment (such as affecting heat dissipation, causing dirty contacts of electrical equipment and poor contact, etc.). Specifically, after the staff turns on the power switches of the liquid pump 8 and the cooling fan 9 respectively, the liquid pump 8 extracts the water between the inner and outer layers of the left end of the shell 4, pumps it into the heat pipe 10 through the lower end of the heat pipe 10, and then discharges it from the upper end of the heat pipe 10 into the inner and outer layers of the right end of the shell 4. Since the cooling fan 9 dissipates the water flowing into and out of the heat pipe 10, it can effectively ensure that the water between the inner and outer layers of the shell can achieve a better cooling effect, thereby reducing the temperature in the ring network cabinet body 1. After the power input end of the power module A1 inputs 220V power, the 3 and 4 pins of the power module A1 will output a stable DC 12V power supply into the three power switches and one end of the two reed switches, and the power input end of the SMS module A2. The new model is based on the ring main unit 1, which has all the functions of controlling the operation of electrical equipment of ordinary ring main units (ring main units are widely used, and this article will not go into too much detail). In actual applications, when the remote manager controls the load switch to open through the existing mature Internet of Things technology, the operating handle 6 of the load switch moves upward, and the upper magnet 3 will approach the reed switch GH1, and the internal contacts of the reed switch GH1 will close. In this way, the low level output from the 4th pin of the power module A1 will enter the 3rd pin of the SMS module A2 through the reed switch GH1, so the SMS module A2 will send out the first SMS stored internally. After receiving the SMS, the remote manager will be able to know that the remote control is successful at the first time (no SMS means failure, and the staff can perform remote control again). When the remote manager controls the load switch to close, the operating handle 6 of the load switch moves downward, the lower end magnet 3 will approach the reed switch GH2, and the internal contacts of the reed switch GH2 will close. In this way, the low level output from the 4th pin of the power module A1 will enter the 4th pin of the SMS module A2 through the reed switch GH2, so the SMS module A2 will send out the second SMS stored internally. After receiving the SMS, the remote manager will know that the remote control is successful at the first time (no SMS means failure, and the staff can perform remote control again). In actual application, after all the cabinet doors are closed, the internal contacts of the three power switches S1, S2, and S3 are not closed. In this way, the 5th pin of the SMS module A2 does not input a low-level signal, and the SMS module A2 does not send SMS. After all the cabinet doors are closed, the internal contacts of the three power switches S1, S2, and S3 are not closed. In this way, the 5th pin of the SMS module A2 does not input a low-level signal, and the SMS module A2 does not send SMS.In actual applications, after any cabinet door is opened, as long as the internal contacts of any power switch S1 or S2, S3 are closed, the low level output from pin 4 of the power module A1 will enter pin 5 of the SMS module A2 through the power switch S1 or S2, S3. Then, the SMS module A2 will send out the third SMS stored internally. After receiving the SMS, the remote manager will be able to find out at the first time that a cabinet door is not closed properly, and can take targeted measures later to ensure safe and stable power supply (when the relevant manager opens the cabinet door himself or the SMS module sends a text message, the manager does not need to take any action). The SMS module A2 is a SMS alarm module of model GSM800. The finished SMS alarm module has two power input terminals 1 and 2, and signal input ports 3-8. After a low-level signal is input to each signal input port, the finished SMS alarm module will send a text message via the wireless mobile network. The SMS alarm module stores text messages. In this embodiment, "closing success", "opening success", and "door not closed" are stored respectively. After low-level signals are input to the signal input ports 3, 4, and 5 of the SMS alarm module respectively, the SMS alarm module can send a text message respectively; the cooling fan 10 has a power of 40W and a voltage of 220W AC; the liquid pump 8 is an electric self-priming water pump with a power of 80W and a voltage of 220V AC.
