Description

Technical Field

[0001] This utility model relates to the field of power distribution terminal technology, specifically to DTU smart grid power distribution terminal. Background Technology

[0002] The DTU (Distribution Terminal Unit) is a terminal device specifically designed for distribution network automation. Its core strength lies in its powerful data acquisition and transmission capabilities. It is widely deployed at various nodes in the distribution network, such as substations, ring main units, switching stations, and line ends. By monitoring and collecting key data such as voltage, current, power factor, and switch status in real time, it provides a comprehensive information foundation for distribution network operation and management.

[0003] Most DTU smart grid distribution terminals currently on the market are similar in overall structure, with plastic or metal shells as the main body and an operation panel with a display screen at the front. The internal motherboard carries multiple modules such as data acquisition, data storage, data transmission, and remote control. However, there are some functional deficiencies in actual use, which have room for improvement. For example, as a live-line detection device, the DTU smart grid distribution terminal is quite sensitive to air humidity, especially in summer when the air humidity is high. Once the inside of the device becomes damp and condensed, short circuit faults can easily occur. Currently, the solution is to put moisture-absorbing and dehumidifying bags inside. However, directly placing the bags takes up internal space, and their position is not fixed, which can easily affect the internal components of the device. Therefore, it does not have the function of internal moisture absorption and dehumidification.

[0004] Now, a new type of DTU smart grid distribution terminal is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a DTU smart grid distribution terminal to solve the problem mentioned in the background art of not having internal moisture absorption and dehumidification functions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a DTU smart grid distribution terminal, comprising a first housing, a circuit board fixedly connected to the rear end inside the first housing, a central control module fixedly connected to the middle position of the front end of the circuit board, a data acquisition module disposed at the bottom left side of the front end of the circuit board, a data storage module fixedly connected to the top left side of the front end of the circuit board, a data transmission module fixedly connected to the top right side of the front end of the circuit board, a remote control module disposed at the bottom right side of the front end of the circuit board, a sealing door hinged to the left side of the front end of the first housing, a control panel fixedly connected to the front end of the sealing door, a terminal block disposed at the rear end of the first housing, and a moisture-proof component disposed at the bottom front end of the sealing door to keep the inside of the device dry.

[0007] The moisture-proof component includes a stainless steel tube, which is fixedly connected to the bottom of the front end of the sealed door. A water-absorbing resin rod is horizontally placed inside the sealed door. Side plugs are provided on the left and right sides of the stainless steel tube, and a magnetic head is fixedly connected to the side plug near the stainless steel tube.

[0008] As a further technical solution of this utility model, the surface of the stainless steel tube is provided with multiple sets of small holes, which penetrate both the inner and outer surfaces of the stainless steel tube.

[0009] As a further technical solution of this utility model, the outer diameter of the water-absorbing resin rod is smaller than the inner diameter of the stainless steel tube, and the water-absorbing resin rod can slide left and right along the inside of the stainless steel tube.

[0010] As a further technical solution of this utility model, the outer diameter of the magnetic suction head is consistent with the inner diameter of the stainless steel tube, and the side plugs are symmetrically distributed about the vertical center line of the stainless steel tube.

[0011] As a further technical solution of this utility model, a second housing is fixedly connected to the top of the first housing, a manual switch button is provided on the left side of the front end of the second housing, a photosensitive switch is provided on the right side of the front end of the second housing, and an LED light board is fixedly connected to the bottom of the second housing.

[0012] As a further technical solution of this utility model, the bottom end of the second housing is higher than the top end of the circuit board, and the circuit board, manual switch button, photosensitive switch and LED light board are electrically connected.

[0013] As a further technical solution of this utility model, a third housing is fixedly connected to the upper and lower ends of the front right side of the first housing, a pressure sensor is installed at the top inside the third housing, and a buzzer is fixedly connected to the bottom inside the third housing.

[0014] As a further technical solution of this utility model, the front ends of the first housing and the third housing are flush, and the circuit board, pressure sensor and buzzer are electrically connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the DTU smart grid distribution terminal not only realizes the function of internal moisture absorption and dehumidification, but also realizes the function of internal lighting, and also realizes the function of sealing failure reminder;

[0016] (1) By setting up a stainless steel pipe, water-absorbing resin rod, side plugs and magnetic head, when in use, the data acquisition module collects various analog quantities such as voltage and current, and digital quantities such as switch position and protection action signal in the distribution network. The data storage module stores them locally and transmits them to the background control center through the data transmission module. During daily use, the sealing door is closed. The water-absorbing resin rod in the stainless steel pipe can quickly capture the moisture inside the first shell and keep it dry. When the water-absorbing resin rod needs to be replaced, the side plugs on both sides can be removed directly for replacement. The magnetic head on the side plugs makes it easy to install and remove. The stainless steel pipe together with the water-absorbing resin rod has a small overall volume and a fixed position, which has no impact on the internal components of the equipment and realizes the function of internal moisture absorption and dehumidification.

[0017] (2) By setting up a second housing, a manual switch button, a photosensitive switch and an LED light panel, when the sealed door needs to be opened for maintenance, as the sealed door is opened, the photosensitive switch senses the change in light and automatically turns on the LED light panel to illuminate the inside of the first housing. The manual switch button makes it convenient to manually control the opening and closing, thus realizing the function of internal lighting.

[0018] (3) By setting a third housing, a pressure sensor and a buzzer, during the operation of the equipment, the sealing door should be in a closed state, while the pressure sensor is in a normally open state. The pressure sensor is pressed by the sealing door, and its pressure is stable in the corresponding range. When the pressure value is significantly lower than the corresponding range threshold, the buzzer sounds to remind the staff to check whether the door is not closed properly, thus realizing the function of reminding for poor sealing.

The stainless steel pipe 6 is fixedly connected to the bottom of the front end of the sealing door 5. A water-absorbing resin rod 7 is horizontally placed inside the sealing door 5. Side plugs 8 are respectively provided on the left and right sides of the stainless steel pipe 6. A magnetic suction head 9 is fixedly connected to the side of the side plug 8 near the stainless steel pipe 6.

[0029] The stainless steel tube 6 has multiple sets of small holes on its surface, which penetrate both the inner and outer surfaces of the stainless steel tube 6.

The outer diameter of the magnetic head 9 is the same as the inner diameter of the stainless steel tube 6. The side plugs 8 are symmetrically distributed about the vertical center line of the stainless steel tube 6, which facilitates moisture absorption and dehumidification.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the water-absorbing resin rod 7 inside the stainless steel tube 6 can quickly capture the moisture inside the first housing 1, keeping it dry. When the water-absorbing resin rod 7 needs to be replaced, the side plugs 8 on both sides can be removed directly for replacement. The magnetic head 9 on the side plug 8 facilitates its installation and removal. The stainless steel tube 6 together with the water-absorbing resin rod 7 has a small overall size and a fixed position, and has no impact on the internal components of the equipment.

[0031] The top of the first housing 1 is fixedly connected to the second housing 12.

The stainless steel tube 6, together with the water-absorbing resin rod 7, is small in size and has a fixed position, so it does not affect the internal components of the equipment. When the sealing door 5 needs to be opened for maintenance, as the sealing door 5 is opened, the photosensitive switch 14 senses the change in light and automatically turns on the LED light panel 15 to illuminate the inside of the first housing 1. The manual switch button 13 allows for manual control of opening and closing. During equipment operation, the sealing door 5 should be in a closed state, while the pressure sensor 17 is in a normally open state.
