Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is comprehensively described.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that, when element is called as " setting " at another element, it can be directly can there is element placed in the middle on another element or also.When an element is considered to " be connected " with another element, it can be directly connected to another element, or may there is centering elements simultaneously.
Unless otherwise defined, practical herein all technology and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in instructions of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Multi-face air inlet filter with external filter cloth electric control box comprises the AC380V/4P main switch, AC380V/3P/10A electric motor protecting type miniature circuit breaker, 3P/9A A.C. contactor and the AC380V/3.2 ~ 5A electrothermal relay that set gradually.
Wherein, AC380V/4P main switch connects incoming power, and the output terminal of AC380V/3.2 ~ 5A electrothermal relay connects load.Gear switch and hand switch is also provided with between the miniature circuit breaker of AC220V/1P/6A motor control loop and the secondary coil of 3P/9A A.C. contactor.The input end connection control partial power of gear switch, gear switch output terminal is connected with the outside DCS system of hand switch, multi-face air inlet filter with external filter cloth respectively.Hand switch is connected with 3P/9A A.C. contactor secondary coil with the outside DCS system of multi-face air inlet filter with external filter cloth, and the part output contact of 3P/9A A.C. contactor is connected with the outside DCS system of multi-face air inlet filter with external filter cloth.
Concrete, the hand switch of multi-face air inlet filter with external filter cloth electric control box is made up of two Self-resetting buttons, and one is stop button STP, and another is start button ST.Gear switch comprises manually-stopping-DCS third gear, and namely one represents Non-follow control state, two other represents DCS state of a control and halted state respectively.Manually-stopping-DCS gear switch respectively by power distribution to hand switch, cut-out, the outside DCS system of multi-face air inlet filter with external filter cloth.Multi-face air inlet filter with external filter cloth electric control box also comprises warning indicator, and warning indicator is connected with the outside DCS system of multi-face air inlet filter with external filter cloth.The alerting signal whether filter cloth is finished can pass to DCS system.
In the present embodiment; multi-face air inlet filter with external filter cloth electric control box comprises four groups of AC380V/3P/10A electric motor protecting type miniature circuit breaker, 3P/9A A.C. contactor and AC380V/3.2 ~ 5A electrothermal relays of being connected successively, and each group connects main switch by copper main busbar.Self-resetting button is eight, four red Self-resetting buttons and four green Self-resetting buttons.As shown in the table:
Refer to Fig. 1 to Fig. 4; incoming power is delivered to the copper main busbar of electric control box by AC380V/4P main switch and distribution type miniature circuit breaker; 4 filter cloth driving motors obtain power supply respectively by respective AC380V/3P/10A switch and electric motor protecting type miniature circuit breaker, 3P/9A A.C. contactor and AC380V/3.2 ~ 5A electrothermal relay from copper main busbar; the primary circuit of A.C. contactor is here AC380V, and secondary coil is AC220V.
Wherein, when the switch of manually-stopping-DCS gear rotates to manual gear, i.e. (STP1, ST1, STP2, ST2, STP3, ST3, STP4, ST4) operating personnel start stop button by four on electric control box panel group, carry out startup and the shut-down operation of four filter cloth motor respectively.When pressing ST1 button, 1ST switch can close, and now, 1KM coil can conducting make 1KM2 and KM close, thus filter cloth motor is just come into operation.When release button, 1ST switch can disconnect, but coil 1KM still can conducting.When pressing STP1 button, 1STP switch can disconnect, and coil cannot be connected, and filter cloth motor decommissions.In like manner known, other three groups of control knobs control the startup of corresponding three filter cloth motor and shut-down operation.When manual gear, the distant place controlling functions of DCS is invalid.
Wherein, when the switch of manually-stopping-DCS gear rotates to DCS gear, operating personnel in pulpit by four groups of startups of DCS system, stopping I/O point (i.e. 1DCS1,1DCS2,2DCS1,2DCS2,3DCS1,3DCS2,4DCS1,4DCS2), can carry out startup and the shut-down operation of four filter cloth motor respectively.During DCS gear, the field control function of manual gear is invalid.
Concrete, when the switch of manually-stopping-DCS gear rotates to stopping gear, electric control box cannot carry out manually and DCS remote operation.During this gear, operating personnel can carry out the work such as maintenance and cleaning of filtrator, avoid the hidden danger that maloperation brings.
Wherein, when switch be in manually or DCS gear time, all can transmit to DCS system the alerting signal the etc. whether status signal of motor, switch positions signal and filter cloth use.
In a word, principle of work of the present utility model is exactly: by three station switches of electric control box, carries out the switching controlling place, realizes the functions such as field control, maintenance and distant place control.And can remote monitoring filter cloth driving motor running status, switch place gear and the complete alerting signal of filter cloth.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
