In technique scheme, the long-range on off control case of blower fan of the present utility model can make staff need not device context be gone again to carry out start stop operation in use at ordinary times, has stopped the mistake that some manual operations cause.Because do not need the execute-in-place of personnel protection operator to a certain degree can not be subject to danger yet; and once can also carry out to runnability the details that blower fan electricity consumption situation is understood in real-time monitoring after starting; if there is any situation to take measures the very first time, as much as possible by problem discovery early.
Accompanying drawing explanation
Fig. 1 is the structural representation of the long-range on off control case of the utility model blower fan.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
With reference to Fig. 1, the utility model discloses the long-range on off control case of a kind of blower fan, and its internal structure mainly comprises casing 2, A.C. contactor 6, buffer circuit 3, switching circuit 1, front maintenance port 4, rear maintenance port 5, isolation baffle plate 10, field control button 7 and remote control button 8 etc.Describe the structure of above-mentioned all parts, annexation and effect thereof below in detail.
As shown in Figure 1, A.C. contactor 6, buffer circuit 3 and switching circuit 1 are all arranged in casing 2, and field control button 7 and remote control button 8 are all connected to switching circuit 1, and it is outside to be arranged at casing 2.Casing 2 is a rectangular metal cabinet, and intermediate position is provided with watch window, the position of the corresponding A.C. contactor 6 in position of watch window.Watch window can be observed A.C. contactor 6 easily and whether produce a large amount of electrical spark, thus the accident that can some are avoided in advance serious.
Inner at casing 2, A.C. contactor 6 is arranged on power circuit, and is positioned at the zone line of casing 2.Power line is introduced from the outside of casing 2, and adopt 220V city pressure, power line is connected to the blower fan 11 of casing 2 outside.A.C. contactor 6 is electrically connected buffer circuit 3, and buffer circuit 3 is also electrically connected with switching circuit 1.Buffer circuit 3 is arranged at the stage of casing 2, is convenient to like this utilize casing 2 to carry out ground connection, and switching circuit 1 is arranged at the side of casing 2, near the side of casing 2, so that field control button 7 is connected with the wiring of remote control button 8.
The effect of buffer circuit 3 is that forceful electric power and light current are carried out Secure isolation, and prevent A.C. contactor 6 from causing strong curcent surge switching circuit 1 due to reasons such as electric leakage, short circuits, therefore buffer circuit 3 also has the requirement of ground connection.On the other hand, the effect of switching circuit 1 triggers high/low level signal to control the ON/OFF of A.C. contactor 6.
In addition, be also provided with and isolate baffle plate 10 between A.C. contactor 6 and buffer circuit 3, switching circuit 1, A.C. contactor 6 is kept apart with buffer circuit 3 and switching circuit 1 by isolation baffle plate 10.Due to A.C. contactor 6 easily producing electrical spark, the effect therefore isolating baffle plate 10 prevents electrical spark splashes, especially prevents electrical spark to be splashed on buffer circuit 3 and switching circuit 1.
Continue with reference to Fig. 1, front maintenance port 4 and rear maintenance port 5 are arranged at the both sides of A.C. contactor 6 respectively, front maintenance port 4 is positioned on electric power incoming line, and rear maintenance port 5 is positioned on power outlet, and is respectively equipped with air-break switch in front maintenance port 4 and rear maintenance port 5.
The effect of front maintenance port 4 and rear maintenance port 5 is to provide artificial maintenance, and front maintenance port 4 is provided with the elongation line keeping in repair port 5 after directly connecting.When workman overhauls, elongation line can be utilized to be connected with rear maintenance port 5 by front maintenance port 4, by A.C. contactor 6 short circuit, thus while can keeping in repair A.C. contactor 6, not affect the work of blower fan 11.
In addition, due to the setting of air-break switch, under the state of not overhauling, front maintenance port 4 and rear maintenance port 5 also acts as the function of safety fuse cutout.
Switching circuit 1 is also provided with the control port that can be connected with rear maintenance port 5 with front maintenance port 4, and control port is provided with voltage changing module 9.In specific maintenance situation, switching circuit 1 and front maintenance port 4/ can be keeped in repair port 5 afterwards and be connected, coordinate above-mentioned front maintenance port 4 to be directly connected with rear maintenance port 5, thus can overhaul coordinating in interim for switching circuit 1 put in circuit.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
