Description

Technical Field

[0001] This invention relates to the field of transformer substation line loss detection technology, and in particular to a transformer substation line loss detection device for a distribution network. Background Technology

[0002] As a crucial link connecting the transmission network and users in the power system, the stability and efficiency of the distribution network's operation directly impact the quality and efficiency of power supply. In the daily operation and maintenance of the distribution network system, distribution line loss is one of the core indicators reflecting the economic efficiency, management level, and equipment health status of the distribution area. To accurately grasp the actual situation of distribution line loss, staff need to use specialized line loss detection devices to collect and analyze data on core equipment such as transformers within the distribution area. By acquiring key data such as voltage, current, and power, they can comprehensively determine the causes and extent of line loss, providing crucial data support for line loss mitigation, equipment maintenance, and grid optimization.

[0003] Currently, most widely used distribution network substation line loss detection devices on the market adopt a rigid shell structure design, with the overall material being hard and lacking elastic cushioning. However, the working environment of distribution network substations is complex and diverse. During outdoor operations, inspection personnel often need to work in narrow and rugged areas such as transformer platforms and outdoor distribution boxes. The detection devices are inevitably affected by external forces such as collisions and compression, and may even be accidentally dropped.

[0004] Because existing detection devices lack effective buffer protection structures, when the device is subjected to collisions or drops, the impact force directly acts on the rigid outer shell and the internal line loss detection instrument. This can lead to malfunctions such as solder joint detachment and component damage to the precision electronic components inside the instrument. In severe cases, it can even cause the outer shell to crack or deform, directly affecting the normal performance of the detection device. Furthermore, damaged detection devices not only increase the cost of equipment repair and replacement, but also interrupt on-site line loss detection work due to equipment failure, delaying the progress of line loss analysis and mitigation in the distribution network area, and adversely affecting the efficient operation and maintenance of the distribution network area.

[0005] Therefore, there is an urgent need for a distribution network area line loss detection device with buffer protection function to solve the technical problems of poor protection effect and easy collision damage of existing devices. Summary of the Invention

[0006] The purpose of this invention is to provide a distribution network transformer area line loss detection device that can provide a buffer function, reduce the probability of damage to the internal line loss detection instrument after the device is dropped or collided, and thereby reduce the error and other adverse effects on the detection.

[0007] The present invention adopts the following technical solution: A distribution network transformer area line loss detection device includes a housing, a line loss detection instrument is installed inside the housing, a top cover is hinged to the housing, and buffer grooves are vertically opened at the four corners of the housing. Each buffer groove is provided with a buffer part, and each buffer part protrudes from two adjacent sides of the housing. The height of each buffer part is not less than the height of the buffer groove, and the top of the buffer part does not protrude from the top surface of the housing.

[0008] Preferably, the height of the buffer section is greater than the height of the buffer groove.

[0009] Preferably, the top of the buffer portion is flush with the top surface of the housing.

[0010] Preferably, the buffer portion is arc-shaped.

[0011] Preferably, a buffer cavity is formed between the buffer portion and the buffer groove, and the buffer cavity is in communication with the interior of the housing.

[0012] Preferably, a buffer block is provided inside the buffer cavity, and the buffer block abuts against the corner of the line loss detection instrument through the conductive area between the buffer cavity and the housing.

[0013] Preferably, multiple buffer blocks are spaced apart along the height direction of the buffer cavity.

[0014] Preferably, the buffer block has multiple through holes.

[0015] Preferably, the buffer portion is detachably connected to the housing.

[0016] Preferably, the top cover is provided with buffer grooves at the four corners, and the buffer parts are provided in the buffer grooves.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows: This invention features a buffer section protruding from two adjacent sides of the housing, with a height not less than the height of the buffer groove. When the detection device encounters collisions, compression, or accidental drops in complex outdoor working environments, the buffer section will be the first to contact the object or the ground. The buffer section can absorb and disperse the impact force generated during collisions and drops through its own deformation, preventing the impact force from directly acting on the housing and the internal line loss detection instrument. This effectively prevents malfunctions such as solder joint detachment and component damage to internal precision electronic components, while also preventing cracking and deformation of the housing. This fundamentally ensures the normal performance of the detection device and significantly reduces the probability of equipment damage due to external forces. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, the present invention discloses a distribution network area line loss detection device, comprising a housing 1, a line loss detection instrument 2 disposed within the housing 1, a top cover 3 hinged to the housing 1, and buffer grooves 4 vertically extending through each of the four corners of the housing 1. The buffer grooves 4 extend to the sides of each corner edge of the housing 1, and each buffer groove 4 contains a buffer part 5. The buffer part 5 is made of a high-molecular elastic material with good elasticity, buffering performance, and insulation properties, preferably one of natural rubber, nitrile rubber, silicone rubber, thermoplastic elastomer TPE / TPR, high-elastic EVA foam, or polyurethane PU foam. These materials have moderate elasticity and strong impact resistance, and can effectively absorb and disperse the impact force through their own elastic deformation when subjected to collision or drop impact, preventing rigid impact from being directly transmitted to the housing 1 and the internal line loss detection instrument 2. Meanwhile, all the above materials possess excellent electrical insulation properties, meeting the safety requirements of power distribution network field operations. They also exhibit good wear resistance and weather resistance, adapting to complex and harsh outdoor working environments. Long-term use does not easily lead to aging, cracking, or failure, ensuring the stability and reliability of the buffer protection structure. Preferably, buffer grooves 4 are also provided at the four corners of the top cover 3, and buffer sections 5 are provided within the buffer grooves 4 to provide buffer protection during the handling of the device.

[0020] In this invention, each buffer part 5 protrudes from two adjacent sides of the housing 1. This design allows the buffer part 5 to protect the device from multiple directions, making it well-suited for narrow and rugged outdoor working environments such as transformer platforms and outdoor distribution boxes, thus improving the adaptability and convenience of the testing device in practical applications. Furthermore, in the event of a collision, compression, or accidental drop, the buffer part 5 will be the first to contact the object or the ground. The buffer part 5 can absorb and disperse the impact force generated during the collision and drop through its own deformation, preventing the impact force from directly acting on the housing 1 and the internal line loss detection instrument 2.

[0021] Furthermore, in this invention, the height of each buffer part 5 is not less than the height of the buffer groove 4, preferably the height of the buffer part 5 is greater than the height of the buffer groove 4, and the top of the buffer part 5 does not protrude from the top surface of the housing 1. Preferably, the top of the buffer part 5 is flush with the top surface of the housing 1 to ensure the normal opening and closing of the top cover 3. At this time, the bottom of the buffer part 5 protrudes from the ground of the housing 1, which can ensure that when the device falls vertically, the bottom of the buffer part 5 contacts the ground first, thus playing a buffering role.

[0022] Furthermore, in this invention, the buffer part 5 is preferably configured as an arc shape to achieve a transitional connection between adjacent sides of the housing 1. The surface of the arc-shaped buffer part 5 is smoothly transitioned without sharp edges. When the detection device collides or falls, it can evenly disperse the concentrated impact force along the arc surface, avoiding stress concentration that could lead to excessive local force and damage to the housing 1 or the buffer part 5 itself, further improving the buffering energy absorption effect. In addition, the arc-shaped structure can simultaneously provide all-round protection for two adjacent sides of the housing 1. Regardless of whether the device is side-impacted, obliquely impacted, or lands on a corner from any angle, the arc surface can be the first to contact and absorb the force. Compared with right-angled and angular structures, it can avoid the housing 1 from being directly impacted to a greater extent, providing a wider protection range and stronger adaptability. Preferably, the buffer part 5 is detachably connected to the housing 1, facilitating targeted inspection and replacement and reducing maintenance and usage costs. Specifically, mounting grooves 8 can be provided on the walls of the housing 1 on both sides of the buffer groove 4, and mounting sliders 9 can be provided on the buffer part 5. The sliding connection between the mounting sliders 9 and the mounting grooves 8 enables a quick connection between the buffer part 5 and the housing 1.

[0023] Furthermore, a buffer cavity is formed between the buffer section 5 and the buffer groove 4, providing a certain deformation space for the buffer section 5. When the device is subjected to collision or drop impact, the buffer section 5 can generate controllable compression deformation into the buffer cavity under the impact force, thereby further absorbing and dissipating impact energy. In addition, buffer blocks 6 are also provided in the buffer cavity. The shape of each buffer block 6 matches the shape of the buffer cavity. The buffer blocks 6 are tightly set in the buffer cavity, and multiple buffer blocks 6 are spaced apart along the height direction of the buffer cavity. By setting buffer blocks 6 in the buffer cavity, the overall impact resistance and energy absorption effect can be further enhanced on the basis of the elastic buffering of the buffer section 5 itself, effectively improving the device's protective ability when subjected to collision, compression or drop. The buffer blocks 6 fit tightly with the buffer cavity, providing reliable support for the buffer section 5, preventing the buffer section 5 from excessively deforming and failing under large impact, and ensuring that the buffering process is stable and controllable. Multiple buffer blocks 6 are spaced apart along the height direction, which can retain corresponding deformation gaps in the buffer cavity, so that the buffer part 5 still has sufficient deformation space when under pressure, and will not lose its elastic buffering capacity due to the full filling of the buffer blocks 6, thus taking into account both support strength and deformation requirements.

[0024] Furthermore, multiple through holes 7 are provided through the buffer block 6, and heat dissipation holes are provided between the buffer cavity and the housing 1. The line loss detection instrument 2 generates heat during continuous operation. This structure allows the inner cavity of the housing 1, the heat dissipation holes, the buffer cavity, and the through holes 7 on the buffer block 6 to be interconnected, forming a continuous and unobstructed heat dissipation airflow channel, effectively improving the overall heat dissipation efficiency of the device. The heat generated by the instrument can enter the buffer cavity through the heat dissipation holes and be quickly dissipated outwards through the multiple through holes 7 on the buffer block 6, preventing heat accumulation inside the housing 1 and causing excessively high temperatures in the internal electronic components. This ensures the stable operation of the line loss detection instrument 2 during long-term field testing operations and prevents problems such as malfunctions, decreased accuracy, or accelerated component aging caused by overheating. At the same time, the multiple through holes 7, while ensuring heat dissipation, do not weaken the structural strength and buffering performance of the buffer block 6 itself, and can still effectively absorb and transfer impact energy. The buffer chamber is connected to the interior of the housing 1 through heat dissipation holes, which not only facilitates heat dissipation but also further balances the air pressure inside and outside the housing 1. This makes the buffer part 5 more flexible when it is deformed under pressure, avoiding the impact of air pressure difference on the buffering effect. Thus, while improving the heat dissipation capacity of the device, it also takes into account the stability and reliability of the buffer protection, making the detection device more suitable for the long-term, high-intensity outdoor detection work needs of the power distribution network area.

[0025] The buffer protection structure of this invention can significantly reduce the damage to the detection device caused by collisions and drops, thereby reducing the cost of equipment maintenance and replacement. It eliminates the need for frequent repairs or replacements of damaged devices, reducing material consumption and labor costs during equipment operation and maintenance, saving economic resources for the daily operation and maintenance of the power distribution network area, and improving the overall economic efficiency of the line loss detection device. The top of the buffer section 5 does not protrude from the top surface of the housing 1, ensuring the buffer protection effect of the buffer section 5 without affecting the normal closure of the top cover 3 of the detection device and the compactness of the overall structure, making it easy for testing personnel to carry and operate. The design of the buffer section 5 protruding from the adjacent two sides of the housing 1 can protect the device from multiple directions, fully adapting to narrow and rugged outdoor working environments such as transformer stands and outdoor distribution boxes, improving the adaptability and convenience of the detection device in practical applications.
