Problems solved by technology
[0007] The purpose of the present invention is: in order to solve the vibration of the above-mentioned unit during operation, and because the distance between the two fixed points of the terminal row guide rail in the cabinet is too long, the terminal row will resonate with the running unit and cause the terminal row to contact Bad; due to the vibration during the operation of the unit, the guide rail in the temperature measurement terminal cabinet vibrated, the terminal block for sending the temperature signal was in poor contact, and the unit reported abnormal temperature signals several times during the operation of the unit, which caused serious damage to the safe operation of the unit. Big hidden problem

The invention discloses a rapid fixing device for a control cabinet terminal strip guide rail. The rapid fixing device comprises a control cabinet back plate, a terminal strip fixing guide rail is arranged on the upper end face of the control cabinet back plate, a plurality of mounting grooves are sequentially formed in the terminal strip fixing guide rail, and a plurality of guide rail fixing piers are sequentially arranged on the upper surface of the control cabinet back plate. Meanwhile, the guide rail fixing piers correspond to the mounting grooves in position, and the upper surfaces of the guide rail fixing piers make contact with the bottom end faces of the terminal strip fixing guide rails. According to the invention, self-tapping screws penetrate through the back plate of the control cabinet and are tightened to quickly fix the terminal strip fixing guide rail in the control cabinet, so that the problems of poor contact, signal disconnection, misalignment and the like of a terminal strip for sending temperature quantity upwards caused by resonance jitter of the terminal strip in the operation process of the unit are solved, and the reliability of temperature measurement ofthe unit is practically improved; and meanwhile, common materials in daily life are fully utilized, resource waste in equipment transformation is reduced, the environmental protection property is high, and the transformation effect is good.
Description
technical field [0001] The invention belongs to the technical field of control cabinets, and in particular relates to a fast fixing device for a guide rail of a terminal row of a control cabinet. Background technique [0002] The control cabinet is to assemble the switchgear, measuring instrument, protective device and auxiliary equipment in the closed or semiclosed metal cabinet or on the screen width according to the requirements of electrical wiring. and the safety of surrounding equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation; [0003] There are only two fixed points for the terminal row guide rail and the control cabinet in the temperature measurement terminal cabinet of the unit of Miaowei Hydropower Station. The existing problems are as follows: [0004] (1) The unit will v...
