Technical Field

[0001] The invention relates to a temporary circuit connection device for replacing a bus duct and a use method thereof. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in bus ducts have emerged as a new type of distribution conductor. Compared with traditional cables, bus ducts fully demonstrate their superiority in high-current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise of the connection points at both ends of the bus duct and the plug-in points of the branch ports are greatly reduced. High-quality insulating materials are used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more perfect.

[0003] With the expansion of the factory and the addition of equipment, it is usually necessary to reroute or add lines to the bus duct. When rerouting or adding lines, the circuit of the entire factory needs to be disconnected, and the bus duct at a specific location needs to be cut or ports added.

[0004] However, it usually takes a long time to change or add lines. Long-term power outages will have a great impact on normal production and cause great losses to the factory. Therefore, a temporary circuit connection device for replacing bus duct is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide a temporary circuit connection device for bus duct replacement and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: comprising a sliding bin, wherein a first extension rod and a second extension rod which can reciprocate along the inside of the sliding bin are symmetrically arranged inside the sliding bin, a conductive block is arranged on the first extension rod, and a conductive sheet which can form a complete circuit with the conductive block is arranged inside the second extension rod, and elastic sheets which can connect to the internal circuit of the bus duct are arranged on the surfaces of the conductive block and the conductive sheet.

[0007] Preferably, a slider is provided at the connecting end of the first extension rod, and the conductive block is provided on the surface of the slider.

[0008] Preferably, a slide groove is arranged in the second extension rod, the conductive sheet is arranged on the surface of the slide groove, and the sliding block is arranged in the slide groove.

[0009] Preferably, a resistance block is provided at the blocking end of the sliding chamber surface.

[0010] Preferably, the surfaces of the first extension rod and the second extension rod are both provided with brackets, and the elastic sheet is provided on the surfaces of the brackets.

[0011] Preferably, crushing pieces are arranged on the surfaces of the two conductive blocks, and spring blocks are arranged on the surfaces of the two conductive blocks, and the spring blocks wrap the crushing pieces.

[0012] Preferably, support rods are symmetrically arranged inside the sliding bin, gear blocks are arranged on the surface of the support rods, tooth blocks are arranged on the surfaces of the first extension rod and the second extension rod at positions corresponding to the gear blocks, and the gear blocks are meshed with each other.

[0013] Preferably, a cross bar is provided inside the sliding bin, and limit blocks are symmetrically provided on the surface of the cross bar.

[0014] Preferably, a threaded rod is provided on one side of the surface of the cross bar, a rotating block is provided on the surface of the sliding bin, and the threaded rod is provided on the surface of the rotating block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The entire device can short-circuit the local circuit by connecting in parallel and actively increasing the resistance of the entire device, so there is no need to cut off the power for a long time. It can change or add lines to a specific section of the bus duct. Due to its small current, it increases the safety of operators and reduces the loss of the plant;

[0017] 2. The entire device has a good protection structure. When a problem occurs in the circuit, the entire device will be in a high temperature state. When the temperature of the conductive block rises sharply, the liquid inside the broken piece expands due to the heat, thereby breaking the broken piece. After the two conductive blocks lose their restrictions, the two conductive blocks are pulled away from the surface of the conductive piece under the action of the spring block, thus forming a short circuit and triggering the circuit protection system, thereby protecting the device and the operator.
