Description

Technical Field

[0001] The utility model relates to the technical field of porcelain column type circuit breaker testing, in particular to a movable power supply testing platform for porcelain column type circuit breaker testing. Background Art

[0002] As important high-voltage switchgear in power systems, pole-type circuit breakers are widely used for overload and short-circuit protection, ensuring the safety and reliability of power systems. To ensure the normal and reliable operation of pole-type circuit breakers during use, a series of tests are required to comprehensively verify their performance. Testing pole-type circuit breakers is an important means of ensuring their performance and safety. A test platform is typically used at pole-type circuit breaker testing sites. This platform provides a stable support for the pole-type circuit breaker, preventing inaccurate test data or damage to the equipment due to shaking or tipping during testing.

[0003] A common field test platform for testing live-leg circuit breakers typically consists of a steel frame, columns and beams, rod-shaped porcelain insulator supports, insulating plates and spacers, fixtures and connectors, terminal blocks and cables, measuring instruments and sensors, and safety devices. The rod-shaped porcelain insulator supports the live-leg circuit breaker, while the fixtures and connectors securely fasten it to the test platform. The terminal blocks and cables provide the electrical connection between the test equipment and the circuit breaker. Measuring instruments and sensors monitor and record various parameters and data during the test in real time.

[0004] Traditional field test platforms for porcelain column type circuit breaker tests mostly adopt a fixed design, that is, once installed in place, it is difficult to move, which limits the use site and leads to limited flexibility. In order to solve the above problems, some field test platforms for porcelain column type circuit breaker tests have pulleys installed around the bottom of the test platform, so that the test platform can be moved by the pulleys. The test platform can be moved to different sites for use, which improves the flexibility of the test platform. However, this method requires the use of a power supply during the use of the test platform, and the test platform usually needs to rely on an external power supply. When it is too far away from the power supply, not only a long power cord is required, but also a variety of instruments and cables cannot be carried. For this reason, a movable power supply test platform for porcelain column type circuit breaker test site is proposed. Utility Model Content
