Abstract
The utility model belongs to a dual-pulse and dual-time delay electric time relay, which is used by low-voltage electrical apparatuses. Two groups of electromagnetic clutch mechanisms and two groups of time delay mechanisms recirculate and recurrently send two groups of time delay signal and pulsed signal with different time delaying ranges. The utility model can be used in an electric driving system and an automatic controlling system for the periodic control carried out according to the time program, for example, the metallurgy rubber, the plastics, the heat treatment in the petrochemical industry and all the programme control relative to time. One dual-pulse and dual-time delay electric time relay of the utility model can complete the actions of two electric time relays of the prior art.
Description
Technical field is a low-voltage electrical apparatus under the dipulse dual-delay electric time relay.
The electric time relay basic structure of prior art is made up of micro synchronous motor, gear reduction unit, electromagnetic clutch mechanism, time-delay mechanism and contact system.Its operation principle is: when only connecting the power supply of synchronous motor, and the idle running of motor driven gear decelerator.After relay is accepted input signal, the electromagnetic clutch mechanism action, pass to time-delay mechanism by the rotation of lever harrow gear reduction unit and make its trigger, galianconism (perhaps projection) on time-delay mechanism's central shaft rotates thereupon simultaneously, through the delay time of adjusting in advance, oppress contact system face output signal gradually and finish the time-delay process.
The working method of this structure electric time relay is that on-delay type (as Fig. 1) or outage time lagged type (as Fig. 2) all can not be realized repeating to delay time (can not improving the time control of ground property performance period as Fig. 3) Calipering." common low-tension device and application thereof " (Zhang Guansheng, fourth bright road work, China Machine Press, nineteen eighty-two version) point out: " after repeating time lagged type and being meant energized; the time relay is with the continuous operation again and again of certain cycle " is evaluated as and realizes repeating to delay time and says " this Xian Lu And imperfection " " ... so that can not realize that delay time is the periodicity action of ts " when adopting the control circuit that a time relay forms and the utility model dipulse dual-delay electric time relay time that Calipering can improve ground property performance period that can repeat to delay time is controlled, and makes a relay can shoulder two relay roles.
The structure of dipulse dual-delay electric time relay is made up of drive system, the first electromagnetic clutch mechanism, the second electromagnetic clutch mechanism, first time-delay mechanism, second time-delay mechanism and contact system.
Drive system comprises micro synchronous motor T
D, gear reduction unit, castle wheel initiatively,
The first electromagnetic clutch mechanism comprises the first electromagnet T

The second electromagnetic clutch mechanism comprises the second electromagnet T
2, second lever and starting switch.
Two time-delay mechanisms are made up of first and second passive castle wheel, first and second rotation galianconism, back-moving spring, pointer, dial plate etc. respectively.
The operation principle of dipulse dual-delay electric time relay such as Fig. 4, shown in Figure 5 are described as follows:
When energized, synchronous motor T
D(1) and the first electromagnet T
1(4) be initially located in "on" position, synchronous machine Qi Dong And driven wheel decelerator (2) running, the first electromagnet T simultaneously
1Adhesive, it oppresses interlocking contact system K on the one hand
1The normally-closed contact of ' (3) cuts off the second electromagnet T
2(21 〕 De rotation roads pin down active castle wheel (10) by first lever (5) on the other hand the first passive castle wheel (8), then first time-delay mechanism's trigger are passed in the rotation of gear reduction unit.Through the delay time adjusted in advance (by the first delay time t
Y1Decision) after, the rotation galianconism of first on this mechanism's central shaft (9) moves to certain position compressing contact system K
M1(7) the first pulse signal (t takes place
M1).Then oppress the K of normally-closed contact system again
1(6) cut off T
1Circuit make its release, K simultaneously
1' recover normally off, because the first electromagnet T thereupon
1The effect of inner counter-force, initiatively castle wheel breaks away from the first passive castle wheel, and then first time-delay mechanism restPoses under the effect of back-moving spring.
Behind first time-delay mechanism's trigger to the first electromagnetism T
1Before discharging starting switch Q (24) is closed, along with contact system K
1' closure, the second electromagnet T
2Be initially located in "on" position Xi He And compressing interlocking contact system K
2' (23) pin down initiatively castle wheel by second lever (22), and the second passive castle wheel (17), then second time-delay mechanism's trigger are passed in the rotation of gear reduction unit.Equally through the delay time adjusted in advance (by the second delay time t
Y2Decision) after, the second rotation galianconism (16) moves to certain position compressing contact system K on this mechanism's central shaft
M2(18), the second pulse signal (t takes place
M2).Then oppress the K of normally-closed contact system again
2(19) cut off T
2Circuit makes its release, simultaneously K
2' recovery normally off.At the second electromagnet T
2Under the effect of inner counter-force, initiatively castle wheel breaks away from the second passive castle wheel, and then second time-delay mechanism restPoses under the effect of back-moving spring.
Along with K
2' closed first electromagnet is initially located in logical electricity condition And adhesive action again, and relay begins the work of following one-period, the do action repeatedly because two electromagnetic clutch mechanisms and two time-delay mechanisms cooperatively interact like this, and relay passes through contact system K constantly
M1, K
M2Periodically produce pulse signal, an electric magnetic iron rotation road and the 2nd electric magnetic iron rotation road and two auxiliary relays (12) (11) wherein periodically produce time delayed signal.And the motion of whole system inside is shown by dial plate (15) and pointer respectively, finishes the peculiar dipulse dual-delay of the utility model function.Its working method as shown in Figure 6.
Dipulse dual-delay electric time relay can realize perfectly electric drive system and The periodic time control of automatic control system also can be used with other control apparatuses, Improve automatization level. And simple in structure, stable performance, easy to maintenance, to unit on every side The impact of part and device is littler, can be applicable to that various environment and Games He ， And have manufacturing process Property is good, and volume is little, in light weight, low cost and other advantages.
Dipulse dual-delay electric time relay can be widely used in industry, agricultural, national defence, The other field of scientific research and national economy. For example: metallurgy, rubber, plastics, oil The industry such as worker, heat treatment, all programme-control relevant with the time all may be used it.
Because the utility model is to the significant improvement of prior art on structure and performance, institute All can be on the basis of prior art with manufacturing and designing of dipulse dual-delay electric time relay Upper raising is finished, as the new series of products of electric time relay, the promotion electric equipment products Upgrading.
Hereby it is compared with the prior art as follows to enumerate the utility model:
