Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to a disturbance-free power supply fast switching control device. Background Art

[0002] In petrochemical, metallurgical and other large and medium-sized industrial enterprises, abnormal power outages, large voltage fluctuations or short-term power outages (commonly known as "power swings") are common due to external power grid or internal power supply network failures or abnormalities. Due to the particularity of the process flow of metallurgical and petrochemical enterprises, power supply interruptions or abnormalities often cause equipment shutdown or idling, process interruption or waste, and sometimes even cause serious consequences such as the scrapping of production equipment. At present, in order to ensure the normal operation of production, it is necessary to install a power supply fast and disturbance-free switching control device.

[0003] The existing power fast disturbance-free switching control device is fixed to the wall by using screws to penetrate the mounting holes on the four bottom corners. However, due to the relatively narrow cross-sectional area of ​​some walls and the fact that the mounting holes on the four bottom corners of the power switching device are fixed differently, it is impossible to ensure that each mounting hole can be aligned with the wall, resulting in the problem that the installed power fast disturbance-free switching control device is not firmly fixed and is easy to fall off.

[0004] Secondly, after searching, it was found that a Chinese patent disclosed "A fast and disturbance-free power switching control device for industrial and mining enterprises", and its application number is "202020695636.3". This patent mainly slides the two mounting bars along the slide groove according to the cross-section of the wall where the power switching device is installed. After the two mounting bars slide to a suitable position for installation on the wall, one end of the first locking piece passes through the guide groove and is inserted into the first threaded hole. The abutment block is screwed, and the first locking piece is inserted into the first threaded hole until the first abutment block and the upper surface wall of the mounting plate abut against each other. Then, the screwing of the first abutment block is stopped, so that the mounting bar with a determined position is fixed on the mounting plate, and then the screw is inserted into the wall through the mounting hole with a screw. The distance between the two mounting bars can be flexibly adjusted to adapt to walls with different cross-sectional areas, ensuring that each mounting hole can be aligned with the wall, so that the power control device is firmly fixed; however, this installation method cannot achieve synchronous adjustment, causing inconvenience.
