The specific embodiment
In Fig. 1, " DC/DC Switching Power Supply " is arranged at integrated controller, the part of becoming one controller.Elevator supply is through " power supply input terminal " access, and " current rectifying and wave filtering circuit " of process frequency converter becomes direct current (DC), then is input to " DC/DC Switching Power Supply ", is converted into multi-channel dc power supply, through " control path connection terminal " output.The characteristics of this scheme are that Switching Power Supply has been used frequency converter " current rectifying and wave filtering circuit ", make switching power circuit reduce element, simplify the structure, and can reduce production costs.
Special safety equipment specification regulation: " elevator should possess the mutually disconnected and fault-phase protection function of electric power system, and when mutually disconnected or misphase appear in the elevator supply circuit, elevator should out of service and maintenance halted state "; " the elevator operation is irrelevant with phase sequence, can not establish the fault-phase protection function ".According to this requirement, the Frequency converting driving elevator can only possess phase failure protection function.
In Fig. 1, " open-phase protection circuit " is arranged among integrated controller, replaced in the prior art dislocation phase protective relay in the discrete setting of elevator control cabinet.The input end of " open-phase protection circuit " is connected with " the power supply input terminal " of integrated controller; the application photoelectrical coupler is detected the phase voltage of power supply; when recognize three phase mains wherein one mutually or two-phase while opening circuit; by the disconnected phase signals of " control path connection terminal " output power supply, cut off the supply line of driving motor by the elevator safety circuit be attached thereto.
Embodiment illustrated in fig. 2 and the difference of Fig. 1 are mainly that the input mode of Switching Power Supply is different, and Fig. 1, by " current rectifying and wave filtering circuit " input DC power of frequency converter, adopts " DC/DC Switching Power Supply "; Fig. 2, by " power supply input terminal " input ac power, adopts " AC/DC Switching Power Supply ".Remaining circuit is identical, not at repeated description.
The elevator of switch power supply type shown in Fig. 3 is controlled the embodiment of power supply, is input as the direct current (DC) that frequency converter current rectifying and wave filtering circuit (1) provides, and through DC/DC conv (2), by DC110V and DC24V lead-out terminal (3), is exported afterwards.Because DC110V and the DC24V lead-out terminal (3) of this device have been realized electrical isolation with power supply, its "-" termination enters the ground wire of elevator device, "+" end is linked into respectively microcomputer and controls and call/display circuit (8), vital circuit (9), contactor control circuit (10), brake circuit (11) through fuse (4), (5), (6), (7), the rated current of its fuse is by corresponding load apolegamy.Like this, ground connection or contacting metal member occur and while causing ground connection, line electricity fails to be convened for lack of a quorum and greatly increases, and causes fuse blows, cuts off the power supply of circuit, with this, realizes the control that the elevator drive main frame is shut down, and plays the effect of ground protection when foregoing circuit.
Electric elements operating voltage in the brake circuit of the present embodiment, contactor control circuit and vital circuit is chosen to be DC110V, and microcomputer is controlled with the operating voltage of call/display circuit and is chosen to be DC24V.The apparatus for controlling elevator of prior art is used the alternating current operation contactless switch usually, and this circuit is selected DC operation contactor, and to adapt to the power supply of Switching Power Supply, its running noises lowers, and cost has increased slightly.
In the open-phase detection circuit of Fig. 4, rectifier diode (D1), (D3), current-limiting resistance (R1), (R3), filter capacitor (C1) form the first-phase half-wave rectifying circuit, and rectifier diode (D2), (D3), current-limiting resistance (R2), (R3), filter capacitor (C2) form the second-phase half-wave rectifying circuit; This circuit is used two photoelectrical couplers to be detected input power; the input end of the first photoelectrical coupler (U1), the second photoelectrical coupler (U2) is connected in series respectively current-limiting resistance (R4), (R5) is connected to first-phase, second-phase half-wave rectifying circuit afterwards; (U1), the mouth of (U2) is connected in series; (U1) collecting electrode is received and is controlled power supply (VCC) through phase failure relay (J), and (U2) emitter connects and controls power supply (GED).Filter capacitor (C1) is designed to drive (U1), (U2) operate in saturation 1/40 second to 1/20 second with loading capacity (C2).When power supply is normal, (U1), (U2) maintain saturation conduction, (J) adhesive; When the disconnected phase time of power supply occurs, (U1), (U2) cut-off, (J) discharge.(J-2) contact of phase failure relay (J) is connected to " control path connection terminal ", for elevator safety circuit, is connected in series; Controlled the break-make of light-emitting diode D5 by (J-1) contact, for showing disconnected phase testing result, to facilitate check and maintenance activity.
The application photoelectrical coupler detects, and its mouth has been realized the electrical isolation to power supply, and antijamming capability is strong, has the voltage stabilizing current-limiting function, and working stability is reliable.
Below with embodiment, the present invention has been carried out launching to describe by reference to the accompanying drawings, this description does not have restricted, the embodiment that shown in accompanying drawing, also just the present invention forms, and technical scheme of the present invention is not limited to this.Those of ordinary skill in the art should be understood that, in the situation that do not break away from design philosophy of the present invention, the actual variation on some details of implementing also to have of the present invention.So as long as, aim according to the invention, these variations include within protection scope of the present invention.
