Abstract
The utility model discloses a kind of electrostatic grounding monitor loop warning device, it comprises relay, the input end access electrostatic loop at the two ends of power supply of described relay, first of described relay is often opened output terminal and is connected with red light, the two ends of power supply are incorporated to after described red light serial connection relay, the normally closed output terminal of described relay is connected with green light, the two ends of power supply are incorporated to after described green light serial connection relay, also comprise hummer, the two ends being incorporated to power supply after output terminal is connected in series often opened by described hummer and second of relay.Compared with prior art, automatic alarm when the utility model can disconnect in electrostatic loop, grasps the situation in electrostatic loop in time, uses manpower and material resources sparingly.
Description
Technical field
The utility model electric equipment electrostatic monitoring technique, is specifically related to a kind of for electrostatic grounding monitor loop warning device.
Background technology
So-called electrostatic, a kind of exactly electric charge remained static immobilising electric charge in other words, when accumulation just defines electrostatic on certain object or time surperficial.All Charger transfer can be there is when static electrification object contact zero potential object (ground connection object) or when having the object of potential difference (PD) with it.It is electrostatic height sensible parts that the part that electronics industry factory uses has many, in order to ensure the quality of these electrostatic height sensible parts, usually can set up an electrostatic safety ground networks, setting up multiple electrostatic grounding loop.In order to ensure the security of electrostatic grounding network, need personnel regularly take out stitches measure loop whether disconnect.So, not only need to expend more manpower, and also cannot learn therefore, there is potential safety hazard in time when electrostatic loop disconnects.
Utility model content
The purpose of this utility model is the defect overcoming above-mentioned prior art, provides a kind of electrostatic grounding monitor loop warning device, automatic alarm when can disconnect in electrostatic loop, grasps the situation in electrostatic loop in time, uses manpower and material resources sparingly.
For achieving the above object, the utility model adopts following technical scheme:
Electrostatic grounding monitor loop warning device, it comprises relay, the input end access electrostatic loop at the two ends of power supply of described relay, first of described relay is often opened output terminal and is connected with red light, be incorporated to the two ends of power supply after described red light serial connection relay, the normally closed output terminal of described relay is connected with green light, is incorporated to the two ends of power supply after described green light serial connection relay, also comprise hummer, the two ends being incorporated to power supply after output terminal is connected in series often opened by described hummer and second of relay.
Described relay is electromagnetic relay.
Described power supply is 12V direct supply.
Compared with prior art, the utility model tool has the following advantages:
The utility model utilizes relay the characteristic of " automatic switch " whether to connect to control traffic lights, and when electrostatic return lead is normal, circuit is in on-state, and green light is long bright; When electrostatic return lead disconnects, voltage is added to red light two ends and hummer two ends, when red and hummer is bright, carries joining maintenance personal and carrying out maintenance work in time, by the state in traffic lights monitoring electrostatic loop, reaches automatic monitoring, saves the object of manpower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing identifier declaration:
1, power supply 2, hummer
3, relay 4, red light
5, green light 6, electrostatic loop
Embodiment
Below by specific embodiment, the utility model is further described in detail.
Please refer to Fig. 1, electrostatic grounding monitor loop warning device of the present utility model comprises relay 3, power supply 1, hummer 2, red light 4 and green light 5.The input end access electrostatic loop 6 at the two ends of power supply 1 of described relay 3.First of described relay 3 is often opened output terminal and is connected with red light 4, is incorporated to the two ends of power supply 1 after described red light 4 is connected in series relay 3.The normally closed output terminal of described relay 3 is connected with green light 5, is incorporated to the two ends of power supply 1 after described green light 5 is connected in series relay 3.Described hummer 2 is often opened output terminal with second of relay 3 and is connected, and hummer 2 is incorporated to the two ends of power supply 1 after being connected in series with relay 3.
Preferably, described relay 3 is electromagnetic relay.
Preferably, described power supply 1 is 12V direct supply.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
