The invention discloses an intelligent relay protection tester with a novel assembly structure, which comprises an inner structure and an outer housing clamped on the inner structure, wherein the inner structure comprises a first side panel (1), a second side panel (4) and multiple transverse plates (2), the first side panel (1) and the second side panel (4) have the same structure, the transverse plates (2) are fixed between the first side panel (1) and the second side panel (4) through a thread structure, the cross section of the first side panel (1) is U-shaped, two sides of the top part of the U-shaped first side panel (1) are respectively fixedly connected with an upper connection plate (102) and a lower connection plate (103), the longitudinal directions of the upper connection plate (102) and the lower connection plate (103) are provided with a plurality of through holes (106) for fixing the transverse plates (2), and two ends of each transverse plate (2) are provided with thread holes (204) matched with the thread structure and the through holes. The inner structure of the invention can be correspondingly adjusted according to actual demands, the adaptability is strong, and the constitutive property is strong.
Description
technical field [0001] The invention relates to an intelligent relay protection tester with a novel assembly structure. Background technique [0002] With the rapid development of the national economy, the demand for electricity in all walks of life is increasing, and the requirements for the quality (stability, uninterrupted and accompanying services) of power supply provided by the power supply department are also getting higher and higher. The system has invested heavily in the automation transformation of power generation, transformation and distribution systems. The relay protection device is one of the most important secondary equipments in the power system, and it is the guarantee for the safe operation of the power system. Numerous examples at home and abroad prove that most of the large-scale system accidents involving power outages are directly or indirectly related to incorrect actions of relay protection devices. Therefore, it is an important condition to ensur...
