Description

Technical Field

[0001] This utility model relates to the field of electrical equipment transportation technology, and in particular to a transfer box suitable for gas relays. Background Technology

[0002] As a core non-electrical protection device for oil-immersed power transformers, the gas relay's main function is to monitor gas and oil flow caused by internal transformer faults. When a minor or major gas fault occurs, it can quickly trigger alarm or trip signals, preventing the fault from escalating and causing transformer damage or even power grid accidents. Gas relays require regular offline calibration, typically synchronized with transformer overhauls, and no more than every three years, to ensure their operating characteristics, sensitivity, and reliability meet operational standards. This is a crucial step in ensuring the safe and stable operation of the power system.

[0003] However, the following problems exist in the storage and transportation process after the gas relay is disassembled: (i) Lack of specialized equipment support in the storage and transfer process Currently, after disassembling gas relays at power maintenance sites, they are commonly temporarily stored using simple packaging such as cardboard boxes and foam boxes, or simply placed in the trunk of engineering vehicles mixed with other tools. There is a lack of dedicated transport devices that meet the requirements of the "Regulations on the Management of Power Safety Tools." This temporary storage method fails to consider the structural characteristics of gas relays as precision protective components—they contain sensitive parts such as floats, baffles, and reed switches, and their cast iron casing has limited impact resistance. Dedicated transport equipment should have a graded buffer and shock absorption structure, a moisture-proof sealed cavity, and fixed limiting devices. The existing simple storage and transport methods cannot meet these protection requirements, creating potential hazards for subsequent equipment damage.

[0004] (ii) External environmental factors impair the effectiveness of the submitted test. During transport, gas relays are susceptible to interference from multiple external factors due to a lack of effective protection: First, there is the risk of mechanical impact, such as sudden braking, bumps, or drops and collisions during loading and unloading, which may cause displacement of the internal float, deformation of the reed switch contacts, or loosening of the terminals, leading to drift in the operating value. Second, there is the risk of environmental corrosion, such as when transported outdoors or when the vehicle's trunk is not adequately protected from rain, rain and humidity changes may cause corrosion of internal metal components or a decrease in insulation performance. Third, there is the risk of electromagnetic interference, such as when stored with high-voltage tools, where strong electromagnetic fields may magnetize electronic components such as reed switches. All of these factors may cause inaccurate calibration data during testing. If unqualified components are mistakenly judged as qualified and put back into operation, it will directly weaken the transformer's fault protection capability and constitute a major safety hazard.

[0005] (III) The full life cycle management system has traceability blind spots. The existing management scheme has not yet established a digital traceability system covering the entire lifecycle of gas relays. Specifically: First, basic information management is fragmented; key data such as equipment serial numbers, model specifications, installation dates, and maintenance records rely heavily on paper ledgers or are stored in different systems, failing to achieve a unique "one item, one code" association. Second, there are gaps in traceability; standardized data collection and association mechanisms are lacking for verification reports during installation and commissioning, status assessment records during disassembly, the flow trajectory of equipment undergoing inspection, and scrapping approval processes. Third, status assessment is lagging; it is impossible to predict equipment health trends through traceability data, making it difficult to shift from "periodic maintenance" to "condition-based maintenance." This management model does not meet the requirements for traceability of critical protection equipment and is detrimental to the root cause analysis of equipment failures and the improvement of maintenance efficiency.

[0006] The aforementioned problems in the storage, transportation, and full life-cycle management of gas relays not only affect the accuracy and effectiveness of equipment inspections but also directly threaten the safe operation of transformers. As power systems develop towards higher voltage, larger capacity, and smarter systems, transformers, as core equipment of the power grid, are becoming increasingly important, and the reliability requirements for their protection devices are constantly increasing. Utility Model Content

[0007] To address the aforementioned problems, this utility model proposes a transfer box suitable for gas relays, which can protect gas relays during transfer and storage, preventing them from being damaged during transportation, and has significant engineering practical value.

[0008] The technical solution adopted in this utility model is as follows: A transfer box for gas relays includes an outer shell, an RFID smart terminal, and a clamping structure. The outer shell includes a lid and a body, which are connected by a hinge, and the interior of the body forms a space for placing the gas relay. The RFID smart terminal is embedded in the lid and can read the RFID chip data on the gas relay. The clamping structure includes a telescopic rod and a clamping block. The telescopic rod is located on both sides of the outer shell, and the clamping block can be inserted into the oil inlet / outlet ports on both sides of the gas relay by the axial movement of the telescopic rod, thus fixing the gas relay.

[0009] Furthermore, the clamping block includes a front cylinder and a rear front cylinder. The front cylinder can be embedded into the oil inlet and outlet ports on both sides of the gas relay, and the rear front cylinder is connected to a telescopic rod.

[0010] Furthermore, the size of the front cylinder is smaller than the size of the rear front cylinder.

[0011] Furthermore, the surface of the clamping block is covered with a cushioning material.

[0012] Furthermore, the transfer box also includes an upper liner, which is disposed on the top of the box cover and can fit the top structure of the gas relay.

[0013] Furthermore, the upper liner is made of a cushioning and shock-absorbing material.

[0014] Furthermore, the transfer box also includes a lower liner, which is disposed at the bottom of the box and is adapted to the bottom structural dimensions of the gas relay.

[0015] Furthermore, the lower liner is made of a cushioning and shock-absorbing material.

[0016] Furthermore, two buckles are provided on each side of the outer casing.

[0017] Furthermore, a carrying handle is provided on each side of the outer casing.

[0018] The beneficial effects of this utility model are as follows: 1. Transportation safety: This utility model, through its clamping structure and upper and lower inner lining design, can effectively prevent the gas relay from being damaged by collision or drop during transportation. 2. Full lifecycle management: The RFID smart terminal can read the RFID chip data of the gas relay and can be combined with the management system to realize traceability management of the gas relay's installation, disassembly, inspection, and scrapping. 3. Ease of operation: The design of the buckle and carrying handle makes it easy to open the transfer box and carry it over short distances. At the same time, the upper and lower linings are replaceable, making maintenance convenient. Attached Figure Description
