Description
Technical field
The utility model relates to a kind of monitoring device, particularly a kind of disconnector monitoring device that puts in place that closes a floodgate.
Background technology
The disconnector success ratio less than 100% of once closing a floodgate, because the combined floodgate success ratio of disconnector affects the normal operation of network system, even be related to operating personnel's personal safety, therefore need to confirm to the "on" position of disconnector the interruption of service that causes not in place of avoiding closing a floodgate.Whether in the prior art, transformer station mainly also is based on the switching value of auxiliary contact to the monitoring of disconnector combined floodgate success ratio, and this is a kind of supervisory system based on one-dimensional information, in case break down, then can't successfully judge closing a floodgate.In addition, unattended operation transformer station is to adopt remote control operation, put in place in order to guarantee that disconnector closes a floodgate, also need artificial on-the-spot affirmation, increased the running time of equipment, also cause to realize Unattended remote control truly, greatly restricted the development of intelligent substation control.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and proposes a kind ofly can confirm effectively that disconnector closes a floodgate and successfully put in place, and is simple in structure, the easy to operate disconnector monitoring device that puts in place that closes a floodgate.
The utility model is realized by following approach:
The disconnector monitoring device that puts in place that closes a floodgate, its structural feature is, include angular displacement sensor and data processing equipment, angular displacement sensor includes rotatable parts and fixed part, wherein the shell body of fixed part is fixedly connected with isolated switchgear by securing member, and rotatable parts are connected with the axle head of the rotation execution unit of disconnector;
Data processing equipment includes signal receiving unit, reference cell, comparison process unit and the delivery unit of communicating by letter, and has signal output part on the angular displacement sensor fixed part, and this signal output part is connected with the signal receiving unit of data processing equipment; Signal receiving unit is connected with reference cell with the receiving end of comparison process unit and is connected, and the output terminal of comparison process unit is connected with the communication delivery unit, and the delivery unit of communicating by letter is connected with host computer.
When disconnector is closing a floodgate, the rotatable parts that its rotation execution unit will drive angular displacement sensor rotate with disconnecting link together, at this moment, coil at the sensor fixed part produces 4 ~ 20mA current signal to angular displacement sensor because of the rotation of rotatable parts, current signal increases and increases along with the angle of rotating, and this current signal will send to data processing equipment by the signal output part on the fixed part.
After the signal receiving unit of data processing equipment receives this current signal, this simulating signal is processed, and send to the comparison process unit, the comparison process unit compares the reference signal that arranges in the signal that receives and the reference cell, when the signal that receives is arranging in the scope, confirm that then the disconnector combined floodgate puts in place, and by communication delivery unit transmit an acknowledgment signal to host computer, if the signal that receives is not in the reference signal scope that arranges, it is not in place to illustrate that then disconnector closes a floodgate, and sends the combined floodgate failure signal to host computer by the communication delivery unit.Had the one dimension supervising device to disconnector combined floodgate success ratio in the host computer, it is based on the switching value of auxiliary contact, judge as the second dimension monitoring to disconnector combined floodgate success ratio from the combined floodgate monitoring based on the angle induction amount of angular displacement sensor and host computer receives, only have the two all to be judged as combined floodgate and put in place, could confirm to close a floodgate successfully.
The close a floodgate monitoring device that puts in place of disconnector based on angular displacement sensor described in the utility model provides the second monitor message for transformer station's remote control operation, described monitoring device not only can confirm effectively that the successful combined floodgate of disconnector puts in place, and the artificial on-the-spot cooperating amount when having reduced operation, simple in structure, easy to operate.
The utility model can further be specially:
Described securing member is a kind of screw.
The shell body of the fixed part of angular displacement sensor is to be fixedly connected with isolated switchgear by this screw.
The rotation execution unit of described disconnector or be the isolating switch mechanism connecting rod, or switch-on/off indicator.
Above-mentioned parts all are the execution units that rotate with the disconnector disconnecting link.
The rotatable parts of angular displacement sensor are a kind of rotor, and the axle head of the rotation execution unit of this rotor and disconnector is welded to connect.
Consider between the axle head of angular displacement sensor and the rotation execution unit of disconnector to be connected needs enough reliable, therefore do not take as far as possible third-party connection measure, thereby guarantee that angular displacement sensor can transmit enough high-precision angle displacement amount and judge for two-dimensional signal accurately.
It is the field programmable gate array of Cyclone II EP2C8Q208C8 FPGA that data processing equipment adopts model.
This programmable gate array can be set according to concrete angle displacement, is implemented in the monitoring that the disconnector under the different situations closes a floodgate and puts in place.
Angular displacement sensor can adopt commercially available product, at present according to experiment with to detect what adopt be that model is the sensor of RVIT-15-120.
In sum, the utility model provides a kind of disconnector based on angular displacement sensor monitoring device that puts in place that closes a floodgate, for transformer station's remote control operation provides the second monitor message, described monitoring device not only can confirm effectively that the successful combined floodgate of disconnector puts in place, and the artificial on-the-spot cooperating amount when having reduced operation, simple in structure, easy to operate.
