Abstract
The utility model relates to a remote control protective pressing plate capable of sending position states. The remote control protective pressing plate comprises a control seat, connecting plates, an embedded cylinder, a hinged shaft, a remote control motor and an optoelectronic switch, wherein the control seat is connected with a DTU, and the optoelectronic switch is installed on the upper surface of the control seat; and two sides of the control seat are fixedly equipped with the embedded cylinder and the remote control motor respectively through the connecting plates, a remote control pressing plate is fixedly installed on the hinged shaft connected with the output shaft of the remote control motor, and the optoelectronic switch can be shielded when the remote control pressing plate is swinging. The remote control protective pressing plate has the advantages that the disadvantage that states of the remote control pressing plate cannot be monitored by a distribution automation master station is solved, the position states of the remote control pressing plate in a substation can be monitored by the master station, distribution automation is well achieved, smooth connection of the remote loop and operating state signal transmission of the remote control protective pressing plate are achieved, and treatment efficiency for remote control failures is improved.
Description
Technical field
The utility model belongs to the distribution network technical field of automation, relates to the equipment improvement of electrical power distribution automatization system straighforward operation unit module, especially a kind of distance protection pressing plate that sends location status.
Background technology
In electrical power distribution automatization system, DTU(Distribution Terminal Unit) be its core cell, bearing collection, processing and the transmission work of equipment state signal.Wherein the distance protection pressing plate is as the intermediate link of remote control circuit, is connected among the straighforward operation loop, connecting the handle of DTU and a distant place/on the spot, and whether smooth and easy its connection is is determining whether straighforward operation can be carried out.Closed pair is answered interval distance protection pressing plate, and straighforward operation just can be carried out in this interval, otherwise disconnects pressing plate, even there is operational order can not realize straighforward operation.The distance protection pressing plate plays important protective effect for the debugging that we transform rear whole system, and this link can prevent the remote control switch misoperation.
But as important equipment in protection and debugging, the distance protection pressing plate structure is too oversimplified, unification, can show without any prompt facility the connection state of protecting pressing plate, can transmit the running status of pressing plate without any signal.
The utility model content
The purpose of this utility model is to overcome the weak point of original technology, provides a kind of and improve coefficient of safety, prevents the distance protection pressing plate of the sent location status of remote control misoperation.
The technical scheme that the utility model technical solution problem adopts is:
A kind of distance protection pressing plate that sends location status comprises control block, connecting plate, setting-in cylinder, hinge, remote-control motor and optoelectronic switch, and control block connects DTU, and this control block upper surface is installed optoelectronic switch; In the both sides of control block by connecting plate respectively symmetry be fixed with setting-in cylinder and remote-control motor, be fixedly mounted with a remote control pressing plate on the hinge that this remote-control motor output shaft connects, this remote control pressing plate blocks optoelectronic switch when rotation.
And the free end of described remote control pressing plate is shaped with the setting-in opening, is shaped with embedding slot on the setting-in cylinder, and setting-in opening setting-in enters in embedding slot.
Advantage of the present utility model and good effect are:
1, the utility model is a kind of device that improves coefficient of safety, prevents the remote control misoperation that is series in the straighforward operation loop, this device has been indicated UNICOM's situation of remote control circuit, make the connection status of remote control circuit can carry out remote monitoring, more be beneficial to the processing of automated system fault.
2, the utility model has solved the drawback that the power distribution automation main website can not monitor remote control pressing plate state; make main website can monitor the location status of remote control pressing plate in power distribution station; better accomplish power distribution automation; the connection that has realized remote control circuit is unimpeded; and the transmission of distance protection pressing plate operating state signal, promoted straighforward operation tripping treatment effeciency.
Description of drawings
Fig. 1 is structural front view of the present utility model (pressing plate open mode);
Fig. 2 is for being the vertical view of Fig. 1 (pressing plate setting-in state).
Embodiment:
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.Need to prove, the present embodiment is descriptive, is not determinate, can not limit thus protection range of the present utility model.
A kind of distance protection pressing plate that sends location status comprises control block 4, connecting plate 3, setting-in cylinder 1, hinge 7, remote-control motor 8 and optoelectronic switch 5, and control block connects DTU, and this control block upper surface is installed optoelectronic switch; In the both sides of control block by connecting plate respectively symmetry be fixed with setting-in cylinder and remote-control motor, be fixedly mounted with a remote control pressing plate 6 on the hinge that this remote-control motor output shaft connects, the free end of this remote control pressing plate is shaped with setting-in opening 2.
Be shaped with embedding slot on the setting-in cylinder, so that the made setting-in opening of the free end of remote control pressing plate can enter in embedding slot by setting-in, it is reliable and stable that the maintenance pressing plate is located.
Pressing plate is after setting-in enters embedding slot, and pressing plate will block optoelectronic switch, avoids light to inject.
Operation principle of the present utility model is:
Two cylinder splicing ears of this distance protection pressing plate are the two keys relay loop, one swinging remote control pressing plate is installed between two cylinder splicing ears, be on loop that DTU connects, an optoelectronic switch to be installed, one end hinge of remote control pressing plate is contained on a cylinder splicing ear, but in another cylinder splicing ear of other end setting-in, control breaking of this loop by the photocontrol switching value; In case the remote control pressing plate is closed, stop that light enters, can make two circuit loops with closed simultaneously, report and submit closed node to DTU; And when the remote control pressing plate is opened, having light to inject, disconnected node to DTU is reported and submitted in control signal loop disconnection.Accomplish thus the folding condition of pressing plate is reported and submitted to DTU, then reported and submitted to main website by DTU, realize that main website is to the monitoring of remote control press plate position state in power distribution station.
Claims (2)
1. the distance protection pressing plate that can send location status, comprise control block, connecting plate, setting-in cylinder, hinge, remote-control motor and optoelectronic switch, and control block connects DTU, and this control block upper surface is installed optoelectronic switch; In the both sides of control block by connecting plate respectively symmetry be fixed with setting-in cylinder and remote-control motor, be fixedly mounted with a remote control pressing plate on the hinge that this remote-control motor output shaft connects, this remote control pressing plate blocks optoelectronic switch when rotation.
