Wherein: earth connection 1, ground connection pincers 1-1, low pressure electroscope 2.
Embodiment
The utility model provides many applicable creative concepts, and this creativeness concept can be reflected in a large number of in concrete context.The specific embodiment of describing in following execution mode of the present utility model is only as the exemplary illustration of embodiment of the present utility model, and do not form the restriction to the utility model scope.
Below in conjunction with accompanying drawing and concrete execution mode, the utility model will be further described.
As shown in Figure 1, a kind of low-voltage grounding wire action bars, is characterized in that: comprise earth connection 1 and low pressure electroscope 2, described earth connection 1 comprises ground connection pincers 1-1, and described low pressure electroscope 2 is fixedly connected with described ground connection pincers 1-1.
Earth connection described in the utility model is the earth connection in electric power system in prior art, is the important tool that guarantees staff when unexpectedly there is voltage on the equipment having had a power failure and circuit.By regulation promulgated by the ministries or commissions of the Central Government, earth connection must be 25mm
2above naked copper flexible cord is made.
Described earth connection comprises insulating bar, ground connection pincers and ground connection annealed copper wire.Described ground connection pincers are arranged on the top of described insulating bar, and described ground connection annealed copper wire is connected with described ground connection pincers.Preferably, in the utility model, described ground connection annealed copper wire is multicore transparent insulation copper conductor.
Described low pressure electroscope is for checking voltage to earth conventional electrical safety instrument in the ，Ye Shi family of 250V and following low voltage electrical equipment.It is mainly comprised of parts such as working contact, dropping resistor, neon bulb, springs.It is to utilize electric current to pass through electroscope, human body, the earth to form loop for this electroscope, and its leakage current makes neon bulb build-up of luminance luminous and work.As long as potential difference surpasses certain numerical value (36V is following) between electrified body and the earth, electroscope will send aura, lower than crossing a numerical value, just not luminous, thereby judges that whether low voltage electrical equipment is with voltage.
Described low pressure electroscope also can adopt sound and light alarm type electroscope, and it is mainly by shell, manually form by parts such as test button, working contact, testing circuit, oscillating circuit, light-emitting diode, buzzer, working powers.As long as potential difference surpasses certain numerical value (36V is following) between electrified body and the earth, electroscope will send sound and light alarm, lower than crossing a numerical value, and sound and light alarm not just, thus judge that whether low voltage electrical equipment is with voltage.
As first embodiment of the present utility model, described low pressure electroscope 2 is arranged on the back side of described ground connection pincers 1-1, and described low pressure electroscope 2 is connected by bolt with described ground connection pincers 1-1.
