Description
Technical field
The utility model relates to electric power safety field more particularly to a kind of Antistatic alarms.
Background technique
Service personnel contacts charging equipment by mistake or route is an important factor for threatening service work safety, in service work
In, encountering equipment, there are stronger induced electricity, route moment misdelivery electricity, service personnel to be strayed into the unexpected feelings such as other electrification intervals
Condition, will bring serious security risk to service personnel, and electric shock wound similar together just occurred for Anhui electric power company in 2014
Die accident.The generation of above-mentioned accident, it is no doubt not strong related with service personnel's security concept, but there is also more severe objective originals
Cause.Such as 10kV and distribution network below, have a very wide distribution, it is related to equipment and route is many and diverse, maintenance task is more
It is arduous.Although having had specified in more detail to high-voltage electrical apparatus safe distance in " whole nation is for electricity rules ", such as require 10kV
The safe distance of voltage class service work is 1.0m, similarly, the corresponding safe distance 2.5m of 35kV, 110kV and 220kV,
3.0m and 4.0m, but at the scene in upkeep operation work, operation, task weight, time are excluded especially for distribution network failure
Tightly, service personnel's operating pressure is big, restores electricity as early as possible in order to save time, in addition can take range estimation mode determine safety away from
From in this case, when such as encountering that shaft tower collapses, singlephase earth fault occurs for heavy rain and strong wind weather or route, being easier to
Generation personnel's electric shock accidents.
Research about nearly electric alarming device both at home and abroad originates in the eighties in last century, main thought be using spherical or
Electromagnetic field in its wire-type of electrode inductive spacing, according to Hall effect, electromagnetic field will lead to electrode conductor both ends and Hall electricity occurs
Potential difference is filtered and amplifies to the potential difference, confirms that it is excited by power frequency electric field, then drives sound-light alarm system
System sounds an alarm, and there are power frequency electric fields around suggestion device.
It mainly includes following three classes that is be applied at present, which has the product of nearly electric alarm function: hand-held alarming in short range of electric power
Device, nearly electricity warning wrist-watch and the safety cap equipped with alarming in short range of electric power device.Hand-held alarming in short range of electric power device needs hand-held or interim stickup
On tool and clothing, service personnel's both hands operating space often will affect in actual use, and due to originals such as frictional impacts
Because causing alarm to fall off, security risk is brought.Alarming in short range of electric power wrist-watch is expensive, it is difficult to which large area is universal；Band alarming in short range of electric power
Alarm is generally mounted on the top on the inside of cap by the safety cap of device, brings safety to protective performance of the safety cap to head
Hidden danger, and cap frequently rubs with hair, it is easy to produce static electricity, lead to false alarm.
Summary of the invention
Technical problem to be solved in the utility model is to realize a kind of carry-on alarming device, and service personnel carries its entrance
When electrification in high voltage region, the capable of emitting alarm sounds of device are taken care, and electric shock accidents occurs to avoid service personnel.
To achieve the goals above, the technical solution adopted in the utility model are as follows: a kind of Antistatic alarm, including electric field
Inductor, control circuit and warning circuit, for the electric field induction device output inductive signal to control circuit, the control circuit is defeated
Alarm signal to warning circuit executes out.
The electric field induction device is made of diode D1, flat wave capacitor C1, resistance R1, zener diode D5, two pole
The first probe of pipe D1 input terminal connection, output end are connected to another second probe, the flat wave electricity through resistance R1, zener diode D5
Hold the output end of the one end C1 connection diode D1, the second probe of other end connection, the second probe ground connection.
The control circuit includes battery and field-effect tube V1, and the grid of the field-effect tube V1 is connected to resistance R1 and steady
It presses between diode D5, the drain electrode of the field-effect tube V1 and source electrode are connected with battery, warning circuit.
The control circuit further includes key SA2, and the one end the key SA2 is connected between resistance R1 and diode D1,
The other end connects anode.
The control circuit further includes detection alarm, first probe of detection alarm one end connection, other end connection
Anode.
Key SA1 is connected between first probe and the second probe.
The utility model can ensure service personnel's personal safety, when service personnel carries it into electrification in high voltage region,
To avoid service personnel electric shock accidents occurs for the capable of emitting alarm sounds sound of device, and furthermore the device is small and exquisite reliable, and manufacturing cost is low
It is low, it is easy to popularize.
Detailed description of the invention
The content of width attached drawing every in the utility model specification expression is briefly described below:
Fig. 1 is Antistatic alarm frame principle；
Fig. 2 is Antistatic alarm circuit diagram.
Specific embodiment
The basic principle of the utility model Antistatic alarm is using highly sensitive directional type electric-field sensor, impression
The intensity of AC field around sensor, if experience electric field around sensor and be more than respective strengths, system will immediately
Start sound-light alarm, reminds personnel equipment's electrification, prevent frame such as Fig. 1 institute of the generation whole system of related personnel's electric shock accidents
Show.
Circuit system as shown in Fig. 2, the electric-field sensor circuit of anti-error module by diode D1, flat wave capacitor C1, resistance
R1, zener diode D5 composition, the current potential between the ac input end acquisition ground connection collet and detection contact of rectifier bridge, for feeling
AC field is answered, for charging equipment, which can be DC voltage, pass through flat wave capacitor by D1
It is exported after resistance R1 partial pressure to the grid of field-effect tube V1 after the smothing filtering of C, once ground connection collet stretches to charging equipment, when
When close with equipment live part, since field-effect tube input impedance is high, as long as being slightly proximal to charging equipment, even if not
Contact, fet gate can also obtain enough DC voltages, after DC voltage is more than cut-in voltage threshold value, field-effect
Pipe is connected, and the light emitting diode D4 of warning circuit is driven to glisten, while the active loudspeaker S2 alarm of voice, annunciator electrification,
Forbid it is close, to check the generation of electric shock accidents.It has high sensitivity, can be except equipment safety distance just
Effective alarm is issued, principle is as shown in Figure 2.In addition, system also has self-checking function, pressed by key SA2, output has electricity
The identical signal of state, thus the generation for failure of alarming caused by the damage of anti-locking system
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implements not by above-mentioned
The limitation of mode, as long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not
It is improved the conception and technical scheme of the invention are directly applied to other occasions, the protection scope of the utility model it
It is interior.
