Abstract
The utility model relates to a wind power box type transformer high-voltage side electromagnetic lock power supply circuit, which comprises a wind power box type transformer high-voltage side electromagnetic lock. The wind power box type transformer high-voltage side electromagnetic lock power supply circuit is characterized in that: the power supply end of the electromagnetic lock is connected with a UPS (uninterruptible power supply) through a live displayer; and the output end of the live displayer is provided with three voltage sensors which are used for sensing busbar voltage signals. The UPS is arranged in a wind power box type transformer, so that the electromagnetic lock always has an operating power supply of 220 V, and can only be opened in intervals without live high voltage, the chaotic phenomenon in operating use is avoided and the use safety for users is ensured. The scheme also has the advantages of simplicity and practicality, and easiness in mounting and maintaining and the like, and has good application and popularization value.
Description
Technical field
The utility model relates to a kind of wind-powered electricity generation box type transformer high-pressure side electromagnetic lock power supply circuits.
Background technology
In recent years newly-built many wind power engineerings of China have wherein used a large amount of wind-powered electricity generation 0.69/35kV box type transformer that boosts, and at box type transformer that boosts of each generating blower fan configuration, layout is wider.
" five is anti-" safety problem is arranged in the high-pressure side of box type transformer, and one of them is: the design of high-voltage board must meet the principle of " preventing to enter charged (high pressure) at interval ".That is to say the charged cabinet door that just do not allow to open in the high-voltage board.On the cabinet door, install an electromagnetic lock for this reason.
The power supply of electromagnetic lock design at present is to take from 35kV high-pressure side PT, or takes from the control transformer of 690V side.But all there is outage in these 2 power supplys in the wind-powered electricity generation engineering, make electromagnetic lock not have working power and can not play due " five anti-" function.When the blower fan stoppage in transit, case uprises when pressing on-load switch to open, and whether bushing is no matter charged, and electromagnetic lock all needs open by force with private key, in the reality potential safety hazard that has mistakenly entering charged chamber in service.The personal safety accident that a lot of high pressure get an electric shock had appearred in wind-powered electricity generation industry.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of wind-powered electricity generation box type transformer high-pressure side electromagnetic lock power supply circuits, can guarantee that this electromagnetic lock just can open when high-tension cell is not charged, avoids moving the confusion phenomena in the use, has guaranteed that the user is safe in utilization.
The utility model adopts following scheme to realize: a kind of wind-powered electricity generation box type transformer high-pressure side electromagnetic lock power supply circuits, comprise wind-powered electricity generation box type transformer high-pressure side electromagnetic lock, it is characterized in that: described electromagnetic lock feeder ear is connected with a uninterrupted power supply UPS through an electrification display, and the output of described electrification display is provided with the voltage sensor of three induction bus voltage signals.
In the utility model one embodiment, described voltage sensor is the CGQ2-35 transducer.
In the utility model one embodiment, described electrification display is the DXN-35/Q electrification display.
The utility model is to have disposed uninterrupted power supply UPS in the wind-powered electricity generation box type transformer, makes electromagnetic lock that the operating power of 220V all be arranged all the time, just can open when high-tension cell is not charged, avoids moving the confusion phenomena in the use, has guaranteed that the user is safe in utilization.This programme also has advantages such as simple and practical, that installation and maintenance are easy, has value for applications preferably.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram.
Fig. 2 is the utility model embodiment circuit connection diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model provides a kind of wind-powered electricity generation box type transformer high-pressure side electromagnetic lock power supply circuits, comprise wind-powered electricity generation box type transformer high-pressure side electromagnetic lock, it is characterized in that: described electromagnetic lock feeder ear is connected with a uninterrupted power supply UPS through an electrification display, and the output of described electrification display is provided with the voltage sensor of three induction bus voltage signals.
Concrete, please refer to Fig. 2, in the present embodiment, the output of described uninterrupted power supply UPS is connected to N1, the A1 end of electrification display, described electromagnetic lock feeder ear is connected to the K contact of electrification display, and three voltage sensors of responding to bus A, B, C bus voltage signal are connected respectively to a of electrification display, b, c end.We adopt DXN-35Q electrification display device described in this enforcement, transducer adopts CGQ2-35, these two are used the charged state of circuit and high voltage electric equipment very intuitively, and provide locking control contact and corresponding actuating mechanisms to carry out safety interlocking, prevent electric misoperation.The DXN3-Q high-voltage charge display device is the supporting and additional of " five is anti-".Electromagnetic lock adopts the indoor electromagnetic lock of DSN2 type, and this lock is that a kind of high pressure that prevents closes the electric-controlled mechanical interlock of equipment electric misoperation.This product is widely used in high-voltage board and other needs the local real of safety interlocking
Now interlocking prevents that mistakenly entering charged chamber and misoperation from taking place.Please continue referring to Fig. 2, to electromagnetic lock, open during electrification in high voltage by the K point through electrification display K contact for the uninterrupted 220V power supply of UPS among the figure, and the bright indication of charged display lamp is charged, and the electromagnetic lock coil does not have the 220V power supply; When high pressure was not charged, electrification display did not work, and the K point is closed, and the electromagnetic lock coil obtains the 220V power supply, the manual electromagnetic lock button excitation release of opening the door this moment.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
