Abstract
The utility model provides a fan control return circuit, it includes it sets up fan contactor and the fan start button at fan control return circuit to establish ties, it still including the accuse contact far away of supplementary environmental control unit and distant place handle on the spot, work as distant place grip in local control position on the spot, 1 2 is distant place grip in remote control position on the spot worked as, 3 to the contact switch -on 4 the contact switch -on, among the control circuit, far control contact, distant place handle 3 on the spot 4 contact series -wound loop and fan start button, a distant place be handle 1 on the spot 2 contact series -wound loop parallel connection. The utility model discloses a newly -designed distant place change over switch on the spot that takes, single -control system contact keep the return circuit to adapt to the environment monitor cell design (a fan only provides a control contact that keeps) of most producers, have realized fan control's a distant place / switch on the spot having solved halting problem.
Description
Technical field
This utility model is related to a kind of air-blower control loop applied in intelligent substation.
Background technology
Tradition comprehensive from transformer station, blower fan does not have distant place control, is only controlled on the spot, configuration magnetic starter as control
Loop processed, operations staff manually controls blower fan, as shown in Figure 1:In Fig. 1, SB1 is blower fan start button（Press the button and be followed by
Logical, disconnect after release button）, SB2 is blower fan stop button（Disconnect after pressing the button, connect after release button）.In blower fan not
During operation, when pressing blower fan start button SB1, the control coil energising of blower fan catalyst KM, blower fan catalyst KM auxiliary is touched
Point closure, blower fan start button SB1 returns the powered self-sustaining of rear fan catalyst KM, and a major loop of blower fan catalyst KM touches
Head（It is serially connected with blower fan primary circuit, figure does not show）Closure, blower fan energising runs.In fan operation, press SB2, blower fan
The control coil dead electricity of catalyst KM, blower fan catalyst KM auxiliary contact disconnect, and self-sustaining state is destroyed, blower fan catalyst KM
Major loop contact terminal disconnect, blower fan power-off is out of service, because blower fan catalyst KM auxiliary contact disconnect, after SB2 returns
Blower fan catalyst KM is still in power failure state.
In intelligent substation, auxiliary control system carries out distant place control to blower fan, and a distant place is all controllable on the spot, the environment of auxiliary control
Control unit exports a remote control contact YK, and the remote control contact YK of most auxiliary control producers is single retaining contact（Producer
Original design intent is that when remote control contact YK closes, blower fan starts, and remote control contact YK timesharing blower fan stops）.Common wiring such as Fig. 2
Shown, directly in blower fan start button SB1 loop and meet remote control contact YK, dotted line frame represents YK control contact in the distance.
In blower fan off-duty, when remote control contact YK or blower fan start button SB1 are closed a floodgate, blower fan all starts, and blower fan connects
Tentaculum KM self-sustaining, when SB2 separating brake, closes blower fan.This connection circuit shortcoming is as follows：When blower fan is in running status,
Because blower fan catalyst KM auxiliary contact achieves self-sustaining, remote control contact YK cannot close blower fan.
Wiring is changed to Fig. 2, after remote control contact YK mono- end is connected to SB2, before an end is connected to blower fan start button SB1,
As shown in Figure 3.In blower fan off-duty, when remote control contact YK or blower fan start button SB1 are closed a floodgate, blower fan all starts, blower fan
Catalyst KM self-sustaining, when SB2 separating brake, if far control contact YK is in gate-dividing state, SB2 can close blower fan, if far
Control contact YK is in "on" position, and SB2 cannot close blower fan.And when fan operation, blower fan catalyst KM auxiliary contact self-insurance
Hold, remote control contact YK disconnects and still cannot close blower fan.
Content of the invention
The purpose of this utility model is to provide a kind of air-blower control loop in a blower fan distant place/switch on the spot.
For achieving the above object, this utility model employs the following technical solutions：
A kind of air-blower control loop, it include being arranged in series in the blower fan catalyst in air-blower control loop and blower fan start by
Button, it also includes remote control contact and the distant place handle on the spot of auxiliary environment control unit, and when a distant place, handle is in and controls on the spot on the spot
Position processed, 1-2 contact, when a distant place, handle is in distant place control position, 3-4 contact on the spot；In control loop, remote control
The series loop of handle 1-2 contact is simultaneously on the spot the series loop of handle 3-4 contact and blower fan start button, a distant place on the spot for contact, a distant place
Connection connects.
Using this utility model of technique scheme, switch switch, single control using newly-designed on the spot with a distant place
Contact keeps loop to design come the environmental monitoring unit to adapt to most producers（One blower fan only provides the control of a holding to connect
Point）It is achieved that a distant place for air-blower control/switch on the spot, solve halting problem.
Brief description
Fig. 1 is typical magnetic starter control loop.
Fig. 2 is the magnetic starter remote control loop one controlling contact in parallel.
Fig. 3 is the magnetic starter remote control loop two controlling contact in parallel.
Fig. 4 is schematic diagram of the present utility model.
Specific embodiment
As shown in figure 4, a kind of air-blower control loop, it includes the blower fan catalyst KM being arranged in series in air-blower control loop
With blower fan start button SB1, it also includes the remote control contact YK and distant place handle CK on the spot of auxiliary environment control unit, and a distant place is just
Ground handle CK has four contacts.When a distant place on the spot handle CK be on the spot control position, 1-2 contact, when a distant place on the spot
Handle CK is in distant place control position, 3-4 contact；In control loop, far control contact YK, handle CK 3-4 connects on the spot in a distant place
Handle CK 1-2 contact series loop is connected in parallel on the spot with blower fan start button SB1, a distant place for point series loop.
By improving to air-blower control loop, the series connection handle CK of a distant place/on the spot before control loop, when a distant place/just
Ground handle CK is in control position on the spot, 1-2 contact, and when the handle CK of a distant place/on the spot is in distant place control position, 3-4 connects
Point is connected；Blower fan start button SB1 adopts hold button, in gate-dividing state, presses blower fan start button SB1, blower fan starts
Button SB1 is maintained at "on" position after closing a floodgate, then by once, keeps gate-dividing state after blower fan start button SB1 separating brake, and remote control connects
Point YK according to the original design intent of the air-blower control unit of producer, still for single retaining contact；Because control contact is holding
Contact, cancels blower fan catalyst KM self-holding circuit.
When a distant place/handle CK is in controlled state on the spot on the spot, 1-2 connects, after pressing blower fan start button SB1, wind
Machine start button SB1 is held in "on" position, and blower fan catalyst KM is energized, and blower fan starts, then presses primary air fan start button
SB1, blower fan start button SB1 is held in off state, blower fan catalyst KM dead electricity, and blower fan stops.
When a distant place/handle CK is in distant place control state on the spot, 3-4 connects, and after remote control contact YK closes a floodgate, blower fan contacts
Device KM is energized, and blower fan starts；After remote control contact YK separating brake, blower fan catalyst KM dead electricity, blower fan stops.
