Description
Technical field
The present invention relates to a kind of giant power control, belonged to electronic technology field.
Background technology
The water of giant is provided by high-pressure hydraulic pump; The quality of motor directly influences the pressure of hydraulic giant, and the frequency of utilization of giant is very high, frequent switching between standby and work two states; Workload is very big, thereby causes giant often to break down.
When giant of the prior art had operating state to switch to holding state, electronic electric current and rotating speed all can reduce to zero rapidly, and the hydraulic pressure of water pump not only can not descend then; Have rising to a certain degree on the contrary; Thereby cause giant when holding state switches to operating state, the motor of giant needs high capacity to start, and starting current is big; Cause the regular damage of thermal protector and pressure switch; And the life-span of the motor of giant also can shorten greatly, so not only caused the significantly increase of production cost, and can have a strong impact on the production efficiency of enterprise.
Summary of the invention
Technical problem to be solved by this invention provides a kind of giant power control, realizes that the low load of giant motor starts, and prolongs the useful life of giant greatly, improves the fail safe when using giant.
The technical scheme that the present invention adopted is: a kind of giant power control; Comprise three-terminal polarized plus plug J1 and giant; It is characterized in that: also comprise mains switch J2, starting switch S1, A.C. contactor, solid-state relay J3, the solenoid of said three-terminal polarized plus plug J1 and mains switch J2, starting switch S1, A.C. contactor is formed series loop; The auxiliary contact of said A.C. contactor are connected with the output contact of solid-state relay J3, the motor in series of giant; The input of said solid-state relay J3 and 5V DC power supply, giant sensitive switch S2 form series loop.
Aforesaid giant power control is characterized in that: also be in series with a hot protective relay between said starting switch S1 and the A.C. contactor.
Aforesaid giant power control is characterized in that: also be in series with pressure switch P between said starting switch S1 and the A.C. contactor.
Aforesaid giant power control is characterized in that: also comprise a motor power indicator light parallelly connected with the giant motor.
Aforesaid giant power control is characterized in that: aluminium seat type radiating fin is installed on the said solid-state relay.

Aforesaid giant power control is characterized in that: on the said aluminium seat type radiating fin radiator fan is installed.
The invention has the beneficial effects as follows: the power control circuit through improving giant and the starting switch of giant; Once a plurality of circuit protection modules had been added; The low load that has realized the giant motor starts; Prolonged the useful life of equipment, the fail safe of its power circuit has also obtained the raising of arriving very much.
Description of drawings
The circuit connection diagram that Fig. 1 giant power control part divides;
The analysis chart of motor pressure, rotating speed and electric current during the work of Fig. 2 giant.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1; A kind of giant power control; Comprise three-phase socket J1 and giant; Also comprise mains switch J2, starting switch S1, A.C. contactor, solid-state relay J3, the solenoid of said three-terminal polarized plus plug J1 and Switching Power Supply J2, starting switch S1, A.C. contactor is formed series loop; The auxiliary contact of said A.C. contactor are connected with the output contact of solid-state relay J3, the motor in series of giant; The input of said solid-state relay J3 and 5V DC power supply, giant sensitive switch S2 form series loop; Stuck for preventing the hydraulic giant sensitive switch, water pump is in running order always, between starting switch S1 and A.C. contactor, also is in series with hot protective relay and pressure switch P; Whether the LED light parallelly connected with the giant motor can be in normal operating conditions by the alert giant.
With three-terminal polarized plus plug J1 energized, after high-pressure hydraulic pump connects the water source, mains switch J2 and starting switch S1, the solenoid conducting of A.C. contactor, auxiliary contact closure, thus make the motor of giant be in holding state.
Press the sensitive switch S2 of giant, thereby make the input conducting of solid-state relay J3, output contact is closed, makes the motor of giant in running order.Because the sensitive switch of giant need could conducting by on earth the time with the hydraulic giant trigger, like this, just open fully in the water route of hydraulic giant; When the hydraulic giant trigger breaks off, only need trigger is returned a bit slightly, the sensitive switch of hydraulic giant just breaks off; Motor is just out of service, and at this moment hydraulic pressure almost can be discharged to minimum point, therefore; Be not have pressure in the pump chamber of motor and water pump, can realize low voltage starting thereby motor was started in next time.
The motor speed of giant, electric current and hydraulic pressure are as shown in Figure 2 with the Dynamic Variation Analysis figure under the work two states in standby.
When equipment is short-circuited or electric wire when catching fire, earth leakage protective relay J 2 can trip reliably, and the protection person fully.
Solid-state relay J3 can generate heat during work, will damage if temperature continues rising, therefore aluminium seat type radiating fin is installed on solid-state relay, on aluminium seat type radiating fin, is provided with a plurality of perforates, and radiator fan is installed.
In sum; Power control circuit and the starting switch of giant of giant power control provided by the invention through improving giant; Once a plurality of circuit protection modules had been added; The low load that has realized the giant motor starts, and has prolonged the useful life of equipment, and the fail safe of its power circuit has also obtained the raising of arriving very much.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range by appending claims and equivalent circle thereof.
