The technical scheme of the utility model is that: the utility model provides a two equipment intermittent control devices of adjustable length of time, includes air circuit breaker and time relay, characterized by: the time relay is connected with a power supply through an air circuit breaker; the time relay comprises a first time relay and a second time relay, wherein the communication between the air circuit breaker and the power end of the second time relay is realized through a normally closed contact of the first time relay, the communication between the air circuit breaker and the power end of the first time relay is realized through a normally closed contact of the second time relay, the communication between the air circuit breaker and the power end of the first time relay is realized through a normally open contact of the second time relay, and the second control device is connected in parallel with the power end of the first time relay.
Furthermore, the rear side of the air circuit breaker is communicated with a normally closed contact of the first time relay, a normally closed contact of the second time relay and a normally open contact of the second time relay through a switch and an alternating current relay which are connected in series.
Further, the time relay is JS14P of Zhengtai, the air circuit breaker is DZ 47-60C 20 of Zhengtai, and the alternating current relay is CJX2-0910 of Zhengtai.
Further, the first control device and the second control device are water pumps
The utility model has the advantages that:
1. the utility model discloses a change the electrical control mode of water pump, realize that the automatic intermittent type of two water pumps opens and stops work, reduce people intensity of labour, improve work efficiency.
2. The utility model discloses a connection between electrical equipment such as AC relay, air circuit breaker accomplishes the intermittent type to two water pumps and opens the start-stop operation, prevents that a long-time continuous operation of water pump from causing the damage.
Description of the drawings:
fig. 1 is a circuit diagram of a dual device intermittent control device with adjustable time length.
Fig. 2 is a diagram of the contact connections of the time relay.
The specific implementation mode is as follows:
example (b): see fig. 1 and 2.
The double-equipment intermittent control device with adjustable time length comprises an air circuit breaker and a time relay, wherein the time relay is connected with a power supply through the air circuit breaker; the time relay comprises a first time relay and a second time relay, one normally closed contact of the first time relay realizes the communication between the air circuit breaker and the power end of the second time relay, one normally closed contact of the second time relay realizes the communication between the air circuit breaker and the first control device, one normally open contact of the second time relay realizes the communication between the air circuit breaker and the power end of the first time relay, and the power end of the first time relay is connected with the second control device in parallel; through the electric control mode who changes the water pump, realize the automatic intermittent type of two water pumps and open and stop work, reduce people intensity of labour, improve work efficiency.
The present application will be described in detail below with reference to the drawings and examples.
In fig. 2, the time relay is provided with a base and 8 contacts, wherein 1 and 2 are power access, and 2 groups of one-knife double-throw contacts are 3, 4, 5 and 6, 7 and 8 respectively, wherein 3 is a public end, 4 is a normally open contact, and 5 is a normally closed contact; wherein 6 is a public end, 7 is a normally open contact, and 8 is a normally closed contact.
KT in FIG. 11、KT2And 2 time relays with the model number of JS 14P. When the switch SB is pressed and the coil KA of the AC relay is electrified, the normally open contact is closed to carry out continuous power supply operation, because KT 13 and 5 are NC contacts and KT is supplied2The power supply terminals 1, 2 provide a power supply channel, KT2And 3 and 5, the indicator light is closed and turned on.
When KT2After timing, KT2The 2 groups of contacts are respectively 3 and 5; 6. 8 suction changeTo be disconnected, and 3, 4; 6. 7 is switched off to be absorbed, and 6 and 7 finish KT after the 2 groups of contacts are absorbed1Supply of (KT)1And starting the work timing, turning off the indicator lamps at 3 and 5, and turning off the indicator lamps. Simultaneous KT1Work, make KT1Contact 3, 5 of (KT)2And stopping working. KT (karat)22 sets of contacts return to the original state, KT2And (3) and (5) are closed, and (6) and (7) are opened. The state is returned to the initial state, and the operation is repeated.
After the electricity is normally connected, the indicator lights can be seen to flash and turn off. When the time length is changed, the power supply time is changed, the indicator light is changed into the load, for example, the water pump can see that 2 water pumps work intermittently, and the water pumps work in own time periods respectively.
When the water pump is used, after corresponding electric appliances are connected according to the figure 1, the 2 water pumps can work intermittently by operating according to the operation method of the first embodiment.
