Description

Technical Field

[0001] The utility model relates to the technical field of power distribution terminals, in particular to a power distribution system control terminal device. Background Art

[0002] The distribution switch monitoring terminal (FTU for short) is an intelligent terminal device installed in the distribution room or feeder. Due to its long-term exposure to high humidity environment, its internal components are prone to condensation. (Term explanation: Condensation refers to the phenomenon of water droplets condensing on the surface of an object in a high humidity environment. It is caused by the surface temperature of the object being lower than the dew point temperature in the air. When the water vapor in the air reaches saturation, once it encounters a colder surface, the water vapor will condense into liquid water. This is because the cold surface of the object causes the water vapor to lose heat and cannot be maintained in a gaseous state, thus turning into liquid water droplets. These water droplets are what we usually call "condensation"). After the condensation phenomenon occurs, the insulating material on the surface of the components will be damaged, thereby causing a reduction in insulation performance, thereby damaging the distribution terminal equipment and reducing its service life.

[0003] In order to solve the above technical problems, a Chinese utility model patent with authorization announcement number CN209747907U discloses a power distribution terminal device, including a ring main unit for installing power transmission and distribution equipment; the ring main unit includes a plurality of outgoing switch cabinets, and at least one group of temperature sensors are respectively arranged on the outer wall and the inner wall of the outgoing switch cabinet; a heating device is installed inside the outgoing switch cabinet; the temperature sensor monitors the temperature difference between the inside and outside of the outgoing switch cabinet, and when a certain temperature difference is reached, the heating device is started to generate heat.

[0004] The principle is: at least one set of temperature sensors is set on the outer wall and the inner wall of the outgoing switch cabinet; it can effectively monitor the internal and external temperatures of the outgoing switch cabinet, reduce measurement errors, and when the temperature sensor monitors the internal and external temperature difference of the outgoing switch cabinet and reaches a certain value, the heating device is started to generate heat to eliminate the environment where condensation is generated. The existing technology has the following problems: it uses the temperature sensor to detect the internal and external temperature difference of the switch cabinet, and starts the heating device to balance the internal and external temperature difference, but lacks the specific structure and setting method of the heating device, and only provides an idea of ​​setting the heating device at the bottom of the switch cabinet. It is unknown how to ensure that the temperature inside the switch cabinet can be uniform, so that the temperature in each place in the switch cabinet is balanced and condensation is eliminated.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] See also Figure 1-6 , the utility model provides a technical solution: a power distribution system control terminal device, comprising a cabinet 1 and a power distribution switch monitoring terminal 3 arranged in the cabinet 1;

[0034] The power distribution system control terminal equipment also includes:

[0035] A hot air blower 12 is arranged in the cabinet 1;

[0036] The spiral air duct 13 is arranged on the inner wall of the cabinet 1. A fitting groove 11 that fits the spiral air duct 13 can be opened on the inner wall of the cabinet 1. The spiral air duct 13 is fixed by a pipe bracket, and the air supply port of the hot air blower 12 is connected to the air inlet end of the spiral air duct 13, and the air return port of the hot air blower 12 is connected to the air outlet end of the spiral air duct 13.

[0037] A spiral heat conducting sheet 14, which is disposed at a gap of the spiral air guiding tube 13 and is attached to the spiral air guiding tube 13;

[0038] The spiral guide plate 15 is arranged at the bottom end of the spiral heat conducting plate 14 to guide the water droplets to flow out of the cabinet 1; the lower end of the cabinet 1 is provided with a water outlet pipe 16, and the water outlet pipe 16 is connected to the lowest point of the spiral guide plate 15;

[0039] The above technical solution can be used to evenly heat the interior of the cabinet 1, thereby better eliminating the conditions for condensation. When in use, when the outside temperature is higher than the internal temperature of the cabinet 1, the hot air blower 12 works to generate hot air that is blown into the spiral air duct 13, thereby increasing the temperature of the spiral air duct 13 (here, the temperature can be detected by a temperature sensor, one temperature sensor is set outside the cabinet 1, and the other temperature sensor is set inside the cabinet 1). Since the spiral air duct 13 is evenly wound around the inner wall of the cabinet 1, the interior of the cabinet 1 is evenly heated. Uniform heating is achieved because a spiral heat-conducting sheet 14 is provided at the gap of the spiral air duct 13, so that the spiral heat-conducting sheet 14 is heated synchronously to increase the heating area until the temperature inside the cabinet 1 rises to the same level as the outside temperature, thereby eliminating the conditions for condensation to occur; since a spiral guide plate 15 is provided at the bottom end of the spiral heat-conducting sheet 14, the spiral guide plate 15 can guide the droplets to flow into the water outlet pipe 16, thereby discharging the droplets from the cabinet 1, preventing the droplets from falling on the distribution switch monitoring terminal 3, and improving the service life of the distribution switch monitoring terminal 3.

[0040] Further, such as Figure 3As shown, the power distribution system control terminal device also includes: a bottom plate 2, which is slidably arranged at an opening opened at the bottom of the cabinet 1, and the upper end of the bottom plate 2 is connected to the bottom of the power distribution switch monitoring terminal 3; a driving structure, which is used to drive the bottom plate 2 to move up and down, so as to open or close the cabinet 1; the driving structure includes: a motor 4, which is arranged at the upper end of the cabinet 1; a screw rod 5, one end of which is connected to the output shaft of the motor 4, and the other end of the screw rod 5 passes through the upper end of the cabinet 1 and enters the cabinet 1; a connecting plate 6, which is arranged at the upper end of the bottom plate 2, and the connecting plate 6 is provided with a screw rod groove 7 matched with the screw rod 5;

[0041] The above technical solution is adopted to facilitate opening the distribution switch monitoring terminal 3. When the distribution switch monitoring terminal 3 needs to be opened for operation, the starting motor 4 drives the screw rod 5, the screw rod 5 drives the connecting plate 6 to slide down, and the connecting plate 6 drives the bottom plate 2 to move down, thereby driving the distribution switch monitoring terminal 3 to expose the cabinet 1.

[0042] Further, such as Figure 3 As shown, a guide rod 8 is provided at the upper end of the bottom plate 2, and the guide rod 8 is slidably matched with a guide groove 9 provided at the bottom of the cabinet 1;

[0043] The above technical solution can guide the movement of the bottom plate 2 to prevent the bottom plate 2 from tilting during movement.

[0044] Further, such as Figure 2 As shown, the front hinge of the cabinet 1 is provided with a revolving door 17, and the side of the cabinet 1 is provided with at least two fixing blocks 18, and the fixing blocks 18 are provided with positioning holes 19, and the positioning holes 19 are provided with bolts 10;

[0045] The above technical solution facilitates cleaning of the interior of the cabinet 1. The interior of the cabinet 1 can be cleaned by opening the revolving door 17. During installation, the fixing block 18 is attached to the installation surface, and the bolt 10 is inserted into the positioning hole 19 and screwed into the installation surface to complete the installation.

[0046] Working principle: When in use, when the outside temperature is higher than the temperature inside the cabinet 1, the hot air blower 12 works to generate hot air that is blown into the spiral air duct 13, thereby increasing the temperature of the spiral air duct 13 (here, the temperature can be detected by a temperature sensor, one temperature sensor is set outside the cabinet 1, and the other temperature sensor is set inside the cabinet 1). Since the spiral air duct 13 is evenly wound around the inner wall of the cabinet 1, the inside of the cabinet 1 is evenly heated. Since the spiral heat conducting sheet 14 is set at the gap of the spiral air duct 13, the spiral heat conducting sheet 14 is heated synchronously to increase the heating area until the temperature inside the cabinet 1 rises to the same level as the outside temperature, eliminating the conditions for condensation.

[0047] Since the spiral guide plate 15 is provided at the bottom end of the spiral heat conducting sheet 14, the spiral guide plate 15 can guide the liquid droplets to converge into the water outlet pipe 16, thereby discharging the liquid droplets out of the cabinet 1, preventing the liquid droplets from falling on the distribution switch monitoring terminal 3, thereby improving the service life of the distribution switch monitoring terminal 3;

[0048] When the distribution switch monitoring terminal 3 needs to be opened for operation, the starting motor 4 drives the screw rod 5, the screw rod 5 drives the connecting plate 6 to slide down, and the connecting plate 6 drives the bottom plate 2 to move down, thereby driving the distribution switch monitoring terminal 3 to expose the cabinet 1.

[0049] Thus, a series of tasks are completed, and the circuits, electronic components and modules involved are all prior art, which can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
