TECHNICAL FIELD

[0001] The present application relates to the technical field of power transformer maintenance, in particular to a power transformer safety operation device. BACKGROUND

[0002] In the safety operation device of power transformer (such as manufacturing, assembly or maintenance panel, switch cabinet, etc.), power test clamp is necessary, especially in the link involving electrical test, debugging or maintenance. The following are specific reasons and application scenarios; such as electrical performance test in the manufacturing and assembly stage: before the transformer or switch cabinet leaves the factory, insulation resistance test, ratio test, winding resistance measurement, withstand voltage test, etc. are required. Test clamp is used to connect test instrument and measured part, to ensure safe and reliable electrical contact. When assembling the switch cabinet, it is necessary to verify the opening and closing characteristics of the circuit breaker and disconnector, contact resistance, etc. Test clamp can quickly clamp the conductor to avoid direct contact with the live part. Or in the fault diagnosis stage of maintenance: when maintaining, the electrical parameters of transformer winding, bushing and tap changer need to be detected, and test clamp provides non-destructive connection to avoid frequent disassembly of the wire.

[0003] However, the existing power test clamp lacks spraying function, which cannot immediately remove dirt, oxides or ice coating on the surface of the wire during detection, resulting in increased contact resistance, and additional tools such as cleaning agent and cooling device need to be carried, increasing the work burden. Manual wiping or mechanical deicing is time-consuming and labor-intensive, prolonging the power outage maintenance window.

[0004] Therefore, it is urgent to improve the power test clamp to solve the above problems.

[0005] The purpose of the present application is to provide a power transformer safety operation device, which significantly improves the safety, efficiency and reliability of power transformer maintenance through integrated design, automated operation and multi-functional cooperation. Its advantages not only lie in reducing manual risk and improving operation speed, but also in ensuring maintenance quality and reducing long-term maintenance cost through precise control and flexible adaptation to complex scenarios.

[0006] In order to achieve the above purpose, the main technical scheme adopted by the present application includes: a power transformer safety operation device composed of a mounting frame, a power test clamp arranged on the mounting frame and a driving device, a spraying mechanism and a gas conveying mechanism are further arranged on the mounting frame, and a communication structure is arranged on the power test clamp and communicates with the spraying mechanism and the gas conveying mechanism; The spraying mechanism includes a tank fixed on the mounting frame and a liquid conveying piece, one end of the tank is fixed with a sleeve, a rotating drum is reciprocally arranged in the sleeve, first connecting rods and transmission shafts are respectively fixed at the left and right ends of the rotating drum, a connecting plate is arranged between the first connecting rods and the liquid conveying piece, and an electric telescopic rod is fixed on the back of the mounting frame and fixed on the outer wall of the connecting plate; An elastic abutment rod connected to the rotating drum is provided inside the sleeve, an end of the transmission shaft away from the rotating drum extends to the inside of the tank body, an external spline of the transmission shaft is connected to the stirring rod, and a second connecting rod is provided between the transmission shaft and the stirring rod; The air delivery mechanism includes an air delivery cylinder fixed on the outer wall of the mounting frame, a fan is fixed inside the air delivery cylinder, and a synchronizing member is provided between the fan and the driving device.
