Technical Field
The invention relates to the technical field of electric power overhaul, in particular to a movable low-voltage emergency switch.
Background
At present, part of commissioning equipment is old, the problems of large commissioning time span, various models and inconsistent operation states exist, once the equipment breaks down, the equipment is likely to be directly scrapped, and because the production date of the equipment is early and the models are various, enough spare parts are not available for rapid replacement.
The current solution is to use a wire to jump directly, which has many problems and leaves a potential safety hazard. Firstly, when the wire replaces a switch to be used, various functions are imperfect, the electrical performance is poor, various protections cannot be used, and safety problems are easy to generate. In conclusion, this method can only be used as an emergency option and is not universally applicable.

Detailed Description
The embodiment of the invention provides a mobile low-voltage emergency switch which is used for simplifying the structure, occupying small space and realizing quick assembly and disassembly.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example (b):
referring to fig. 1, fig. 1 is a diagram of a mobile low-voltage emergency switch according to an embodiment of the present invention, including a switch mechanism 1 for controlling on/off of a circuit, and a line connector 2 electrically connected to one side of the switch mechanism 1, where the line connector 2 is a soft copper wire.
Specifically, the switch mechanism 1 is wired by using a soft copper wire, and the surface area of the soft copper wire is far larger than that of the hard copper wire under the condition of the same cross section. The current carrying capacity of the annealed copper wire is greater than that of the hard wire because of the skin effect of alternating current (when alternating current or an alternating electromagnetic field exists in the conductor, the current distribution inside the conductor is uneven, and the current is concentrated on the skin part of the conductor, namely the current is concentrated on a thin layer on the outer surface of the conductor and the current density is larger as the current is closer to the surface of the conductor). The movable low-voltage emergency switch has the advantages of being fast in assembly and disassembly, capable of being repeatedly used and high in universality while having the complete functions of a common low-voltage switch. The mobile low-voltage emergency switch has enough safety margin and electrical performance margin, has wide applicability under the applicable voltage level, and can replace old switches of various types in an emergency mode.
Further, the line connectors 2 are arranged at intervals.
Specifically, as shown in fig. 1, the line connectors 2 are arranged at intervals, so that the installation is convenient.
Further, the number of the line connectors 2 is multiple.
Specifically, line connection spare 2 is the annealed copper line, and many annealed copper line intervals set up, make things convenient for the dismouting, but reuse.
Further, the switch mechanism 1 is a low-voltage emergency switch.
Specifically, the low-voltage emergency switch is used for preventing the electric power equipment from being directly scrapped when the electric power equipment breaks down, and the low-voltage emergency switch is arranged for tripping.
Further, the line connector 2 is connected to an electric device.
In particular, the line connector 2 is connected to the electrical equipment to be protected.
In summary, an embodiment of the present invention provides a mobile low-voltage emergency switch, which includes a switch mechanism for controlling on/off of a circuit, and a line connector electrically connected to two sides of the switch mechanism, where the line connector is a soft copper wire. The wiring of switching mechanism adopts the annealed copper wire, has that the suitability is good, installs and removes fast, and required spatial position is little advantage, and reuse, commonality are strong, and this portable low pressure emergency switch can reduce the power off time by a wide margin, control power off range to show the promotion security.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
