Abstract
The invention discloses an energy-saving lightning protection device of an agricultural irrigation line, and particularly relates to the technical field of earth leakage protection circuits with predetermined delay devices. The energy-saving lightning protection device comprises an alternating current contactor, a delay relay and a residual-current circuit breaker, and a normally-closed contact of the alternating current contactor supplies electricity to the delay relay; the delay relay provides disconnected overload currents for the residual-current circuit breaker through contact attraction after reaching a set time. According to the energy-saving lightning protection device, when no customers use electricity, a power source is disconnected automatically in a delayed mode, losses of an ammeter can be lowered, and damage caused by lightning stroke can also be prevented, and the maintenance cost of agricultural irrigation equipment is lowered.
Description
Technical field
The present invention relates to the leakage protection circuit technical field with predetermined time-delay mechanism.
Background technology
For the agriculture row prepayment metering equipment in field, the most difficult is lack management and be struck by lightning.Field equipment generally lacks personnel to be safeguarded, general user's political consciousness is lower, after electricity consumption, having brushed card just leaves, few people disconnect the residual current circuit breaker of front end, even if be also in electriferous state in the winter in slack season and the equipment in rainy season of seldom use, not only increase electric energy loss (equipment loss) also dangerous; Thunderbolt is also a fatal problem in addition, thunder and lightning may cause later several covers even tens complete equipments burn, every year, because thunderbolt or the long-term charged maintenance of equipment expense of damage that causes of equipment are up to tens0000, the maintenance maintenance of present stage agriculture row equipment has become the heavy burden of power supply department.
Summary of the invention
Technical problem to be solved by this invention is to provide the energy-conservation lightning protection device in a kind of agriculture winding displacement road, can be in there is no client's electricity consumption automatic time delay deenergization, both can reduce ammeter loss, can prevent again broken by lightning, reduce the maintenance cost of agriculture row equipment.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the energy-conservation lightning protection device in a kind of agriculture winding displacement road, comprise A.C. contactor, time-delay relay, residual current circuit breaker, and the normally-closed contact of described A.C. contactor is time-delay relay power supply; Described time-delay relay reaches after setting-up time by contact adhesive provides the overload current of disconnection for residual current circuit breaker.
Further optimize the technical program, the time-delay relay of the energy-conservation lightning protection device in agriculture winding displacement road comprises the NE555 circuit module that RT-6.2-CT mode accesses, and the NE555 circuit module time is set as 0.5-1 hour.
Further optimize the technical program, between 2,6 pins of the NE555 circuit module of the energy-conservation lightning protection device in agriculture winding displacement road and 4 pins, be parallel with the hookup that test switch and 0.5K Ω resistance are connected.
The beneficial effect that adopts technique scheme to produce is: time-delay relay is by the normally-closed contact power supply of A.C. contactor, utilize the automatic trip function of residual current circuit breaker, the delay tripping time is set in 0.5-1 hour, when client is finished after electricity, the power-off of swiping the card, A.C. contactor disconnects, normally-closed contact switches on power, time-delay relay starts timework, after 0.5-1 hour, still there is no client's electricity consumption, the trip circuit of on-delay relay trips by residual current circuit breaker, if there were other client's electricity consumptions within 0.5-1 hour, A.C. contactor adhesive, normally-closed contact disconnects, time-delay relay dump stops work.Can be in there is no client's electricity consumption automatic time delay deenergization, both can reduce ammeter loss, can prevent again broken by lightning, reduced the maintenance cost of agriculture row equipment.
Brief description of the drawings
Fig. 1 is the connection circuit figure of time-delay relay of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, the energy-conservation lightning protection device in agriculture winding displacement road, comprises A.C. contactor, time-delay relay, residual current circuit breaker, and the normally-closed contact of described A.C. contactor is time-delay relay power supply; Described time-delay relay reaches after setting-up time by contact adhesive provides the overload current of disconnection for residual current circuit breaker; The NE555 circuit module that the RT-6.2-CT mode that comprises time-delay relay accesses, the NE555 circuit module time is set as 0.5-1 hour; Between 2,6 pins of NE555 circuit module and 4 pins, be parallel with the hookup that test switch and 0.5K Ω resistance are connected.
380V alternating current is through 0.68 μ f capacitor step-down, and negative half beam warp 12V voltage-stabiliser tube becomes loop to B, and positive axis voltage stabilizing goes out 12V through 1N4007 rectification, 470 μ f filtering output 12V direct currents.After electric current is connected, electric capacity 470 μ f are through 3M Ω resistance charging, and charging starts, and 2,6 jiaos of NE555 are earth potential, 3 jiaos of output high potentials, relay J QX-13F discharge, charge about 0.5-1 hour, 2,6 jiaos rise to 2/3 supply voltage more than, 3 jiaos of output electronegative potentials, relay J QX-13F adhesive, 3.6K Ω/2W resistance is linked between A, B ', residual current circuit breaker action power dump.
S is test button, more than 470 μ f electric capacity charge to rapidly 2/3 supply voltage after pressing, exports electronegative potentials for 3 jiaos, relay J QX-13F adhesive, and 3.6K Ω/2W resistance is linked between A, B ', and residual current circuit breaker tripping operation proves relay and leaks to protect normally.
Time-delay relay is by the normally-closed contact power supply of A.C. contactor, utilize the automatic trip function of residual current circuit breaker, the delay tripping time is set in 0.5-1 hour, when client has watered behind ground, the power-off of swiping the card, A.C. contactor disconnects, normally-closed contact switches on power, time-delay relay starts timework, still there is no client's electricity consumption after 0.5-1 hour, and the trip circuit of on-delay relay trips by residual current circuit breaker, if there were other client's electricity consumptions within 0.5-1 hour, A.C. contactor adhesive, normally-closed contact disconnects, and time-delay relay dump quits work.
