Description
Technical field
The utility model relates to a kind of simple and easy stake resistance on-line measurement appearance; Relate in particular to a kind of on-line measurement appearance of indicating stake resistance, this on-line measurement appearance can be discerned whether safety and the simple and easy online ground resistance measuring instrument device of sound and light alarm is provided of stake resistance under the undesirable situation of stake resistance.
Background technology
At present, the ground resistance measuring instrument that everybody knew all is that price comparison is expensive, and the used electronic component products of ground resistance measuring instrument device is difficult to accomplish on-line monitoring to the having relatively high expectations of field of employment.But grounded screen is required than higher place (such as transformer station, special place, chemical plant) at some; Accomplish definitely meeting the demands of stake resistance again, but do not have the measuring instrument of on-line monitoring resistance at present just can know whether meet the requirements after can only regularly checking by the patrolman; Easy like this causing when stake resistance is undesirable; The staff does not also know, (such as thunderstorm weather, during generation of static electricity) very easily generation accident under the situation of danger.
Summary of the invention
The utility model is in order to overcome the deficiency of prior art, and in order to overcome under the measuring instrument of technology now can not the situation of on-line monitoring to stake resistance, the staff can not know the concrete condition of knowing stake resistance; The utility model provides a kind of simple and easy stake resistance on-line measurement appearance; Whether this measuring instrument not only can the tested stake resistance of detection at any time qualified; And can also under the undesirable situation of stake resistance, send sound and light alarm, in time remind the staff to handle immediately; And it need not provide power supply in addition, installs very convenient.
The utility model solves the technical scheme that its technical matters adopted: a kind of simple and easy stake resistance on-line measurement appearance; Comprise housing; Be provided with integrated control module in the housing; On integrated control module, be connected in parallel to electric capacity, resistance, power supply, voltage tester end, testing current end and earth terminal; Wherein aforesaid power supply is made up of with the solar cell that is connected with lithium battery lithium battery, and integrated control module also is connected with the signal lamp that shows the measuring instrument duty, also is connected with sound-controlled apparatus between signal lamp and the integrated control module.The on-line measurement appearance of the utility model adopts very little, the low-down integrated circuit of voltage of power consumption when measurement of Grounding Resistance, what a stake resistance was set requires standard (be not higher than 10 ohm generally speaking, privileged place is not higher than 4 ohm).When the integrated circuit operate as normal; Basically do not consume how many power supplys, power supply adopts durable lithium battery power supply, by day or have the place of light source to give lithium battery power supply by solar cell; By lithium battery working power is provided at night; When stake resistance is undesirable (such as stake resistance greater than 10 ohm or 4 ohm time), send the sound and light alarm signal by sound-controlled apparatus and signal lamp, can reach the purpose of on-line monitoring stake resistance like this.The integrated control module of this on-line measurement appearance and the connected mode of electric capacity, resistance, power supply, signal lamp and sound-controlled apparatus are that present technique field personnel are known and obviously see the circuit connecting mode of being known.
As the further design to the aforementioned techniques scheme: aforesaid signal lamp is made up of green light that shows the stake resistance operate as normal and the red light that shows the stake resistance non-normal working, and red light is connected with sound-controlled apparatus.
In sum, the stake resistance on-line measurement appearance of the utility model is the tested stake resistance of on-line measurement easily, and adopts ripe integrated circuit; Simple in structure, economical and practical, do not need to provide in addition power supply; Can show at any time whether stake resistance is qualified,, can accomplish sound and light alarm if connecting resistance occurs exceeding standard or be defective; In time remind patrolman's stake resistance whether qualified, and in time handle.The on-line measurement appearance can also arbitrarily be installed according to on-site actual situations, makes things convenient for supervisory personnel's walkaround inspection.
Description of drawings
Fig. 1 is the theory structure of the stake resistance on-line measurement appearance of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further to describe explanation.
The concrete scheme of present embodiment is: a kind of simple and easy stake resistance on-line measurement appearance; As shown in Figure 1; Comprise housing 1; Be provided with integrated control module 2 in the housing, on integrated control module, be connected in parallel to electric capacity 3, resistance 4, power supply, voltage tester end, testing current end and earth terminal, wherein aforesaid power supply is made up of with the solar cell that is connected with lithium battery 6 lithium battery 5 of 4.5V; Integrated control module also is connected with the signal lamp that shows the measuring instrument duty, also is connected with sound-controlled apparatus 7 between signal lamp and the integrated control module; Signal lamp is made up of green light that shows the stake resistance operate as normal 8 and the red light 9 that shows the stake resistance non-normal working, and red light is connected with sound-controlled apparatus.The on-line measurement appearance of present embodiment adopts very little, the low-down integrated circuit of voltage of power consumption when measurement of Grounding Resistance, what a stake resistance was set requires standard (be not higher than 10 ohm generally speaking, privileged place is not higher than 4 ohm).When the integrated circuit operate as normal; Basically do not consume how many power supplys, power supply adopts durable lithium battery power supply, by day or have the place of light source to give lithium battery power supply by solar cell; By lithium battery working power is provided at night; When stake resistance is undesirable (such as stake resistance greater than 10 ohm or 4 ohm time), send the sound and light alarm signal by sound-controlled apparatus and signal lamp, can reach the purpose of on-line monitoring stake resistance like this.
Resistance R 1, R2, R3, R4, R5 and R6 are arranged, capacitor C 1 and C2 among Fig. 1.
