Problems solved by technology
When performing verification or checking on site, maintenance personnel need to first use a multimeter to determine whether the terminal to be operated is live, and then disassemble the secondary wire of the terminal, and the secondary wire is usually closely arranged in the narrow terminal block and slot box During the actual operation, there are four problems: 1. It is necessary to use a multimeter to judge whether the terminal has electricity; 2. It is not easy to pinch the corresponding secondary wire accurately, and it is easy to remove the wire by mistake; 3. It is not easy to restore the secondary wire Align the corresponding port, it is easy to miswire and cause accidents; 4. Due to the inconsistency of the strength or angle of the recovery secondary line, it may lead to virtual wiring
Therefore, the traditional method is not only very inefficient, but also cannot guarantee the safety of on-site work

Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.
[0036] A quick disassembler for substation terminal row secondary wires, characterized in that it consists of a base 1, a clip 3, an upper cover 5, an active rotating part 9, a driven rotating part 19 and a sliding wire clamp part 20, wherein:
[0037] Four lower perforated fins 6 are symmetrically processed on both sides of the upwardly open, rectangular parallelepiped base 1, and a hook 2 is processed on the right side outside the bottom of the base 1. At the right end of the base 1 Fixed pins 4 are provided, and a rectangular baffle 42 is symmetrically processed at the four corners of the bottom surface in the base 1, and four lower semicircular groove plates 44 are respectively processed between the left and right two opposite rectangular baffles 42. The right side of the bottom surface in the seat 1 is processed with...

The invention discloses a rapid replacer for secondary wires of a transformer substation terminal board. The rapid replacer is characterized by comprising a base, a clamp, an upper cover, a driving rotating component, a driven rotating component and a sliding wire clamp component. The rapid replacer can be used for a common transformer substation terminal board through matching of a clamping hook and the clamp; a wire hook has high flexibility, can clamp the secondary wires with different diameters and can penetrate through densely distributed secondary wires; the travel of the sliding wire clamp can be adjusted by adjusting the matching positions of movable slider clamps with a drive belt. The rapid replacer has the advantages that the secondary wires corresponding to terminals can be accurately clamped and can be rapidly pulled out and accurately recovered in a linked manner by loosening or tightening of the terminal screws in a matched manner, besides, whether the terminals are charged is verified, the checking efficiency is improved, safety of fieldwork is guaranteed, labor of workers is saved and the rapid replacer is convenient to use and carry.
Description
technical field [0001] The invention relates to power tools, in particular to a quick dismounter for substation terminal row secondary wires. Background technique [0002] When the maintenance personnel inspect, technically modify or troubleshoot the relay protection device, measurement and control device or power grid safety automatic device in the substation, it involves arranging safety measures for the secondary circuit, restoring safety measures, checking the remote signal, and the safety of the secondary line. Verification and other work, at this time, the maintenance personnel need to manually perform the electrical inspection, temporary disassembly and reinstallation of the secondary line at the terminal block of the screen cabinet. When performing verification or checking on site, maintenance personnel need to first use a multimeter to determine whether the terminal to be operated is live, and then disassemble the secondary wire of the terminal, and the secondary wi...
