Abstract
The utility model discloses an agriculture row circuit energy saving lighting protection device and particularly relates to the technology field of the electric leakage protection circuit with the predetermined delay device. The agriculture row circuit energy saving lighting protection device comprises an AC contactor, a delay relay and an electric breaker. A normally-closed contact of the AC contactor provides power supply to the delay relay; the delay relay operates the overcurrent providing disconnection to the electric leakage circuit breaker after the delay relay achieves the set time. The agriculture row circuit energy saving lighting protection device automatically delays to disconnect the power supply when the user is not using the electricity, which reduces the spoilage of the electricity meter, prevents the damage caused by lighting and reduces the maintenance cost of the agricultural row equipment.
Description
Technical field
The utility model 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.
Utility model content
Technical problem to be solved in the utility model 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, technical solution adopted in the utility model 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 the utility model time-delay relay.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
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.
