500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole
Technical field
The utility model relates to a kind of electric system breaker operating characteristic monitoring system technical field, specifically is a kind of 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole.
Background technology
The separating brake of primary cut-out, closing speed are important technical parameter, and after the primary cut-out switch cubicle was installed, the mechanical property of testing high voltage isolating switch can reflect the quality of its mechanical engagement, electric cooperation and performance.At present, detect separating brake, the closing speed of primary cut-out, generally use grating or accurate swept resistance to detect.The existing product structure is compact inadequately, can only monitor single-phase data, and monitoring capability is accurate inadequately.
The utility model content
The purpose of this real utility model provides a kind of 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole; It can record stroke and the change curve of time, stroke and speed in separating brake, the making process exactly with the resolution of 50 microseconds, grasps the operating mode of isolating switch critical piece in real time.
The utility model achieves the above object through following technical scheme: a kind of 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole; 4U machine frame by CBU-1 master control borad, CBU-2 expansion board, POWER power panel, connection backboard, shaft encoder and 37T is formed, and said shaft encoder is connected respectively to CBU-1 master control borad and CBU-2 expansion board; The CBU-1 master control borad is connected to the ether optical networking; The CBU-1 master control borad is connected to together with the POWER power panel with the CBU-2 expansion board and is connected backboard; Connecting backboard is installed in the 4U machine frame of 37T.
Said shaft encoder is the rotary shaft encoder of storehouse Bole of stroke detection.
The outstanding advantage of the utility model is:
1. compact conformation.Although the function of integrated monitoring three-phase data, the phase monitoring device on its physical dimension, size and the market is compared basically identical.
2. adopt large-scale F PGA, gather the run-length data of 4 frequencys multiplication with the temporal resolution of 50 microseconds, the shake that the divide-shut brake course of action is small is truly reduced.
3. clock and timing are carried out clock alignment with GPS, guarantee the accuracy of clock.
Description of drawings
Fig. 1 is the block diagram of the described 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole of the utility model.
Fig. 2 is the concrete structure and the connected mode synoptic diagram of the described 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole of the utility model.
Embodiment
Below through accompanying drawing and embodiment the technical scheme of the utility model is described further.
A kind of 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole is made up of the 4U machine frame 6 of CBU-1 master control borad 1, CBU-2 expansion board 2, POWER power panel 3, connection backboard 4, shaft encoder 5 and 37T.
Concrete structure and connected mode are: wherein; CBU-1 master control borad 1, CBU-2 expansion board 2 all are plugged on POWER power panel 3 and are connected on the backboard 4, and realize being electrically connected of CBU-1 master control borad 1, CBU-2 expansion board 2 and POWER power panel 3 through the bus that connects on the backboard 4.CBU-1 master control borad 1 set processor plate, A phase RS422 interface board are responsible for the processing and the upload server of all three-phase image data in one, and accomplish the collection of A phase run-length data; CBU-2 expansion board 2 integrates B phase, C phase RS422 interface board, is responsible for accomplishing the collection of B phase, C phase run-length data, and transmits B phase, C phase run-length data on the bus on the backboard 4 to CBU-1 master control borad 1 through connecting.Shaft encoder 5 is the rotary shaft encoder of storehouse Bole of stroke detection.CBU-1 master control borad 1 is uploaded the upper level server through ether optical networking 7 after run-length data is handled.
The method of application of said 500kV breaker trip monitoring device based on the rotary measuring principle of storehouse Bole:
1. at least one joining of three-phase put the rotary shaft encoder of Bole in storage;
2. be installed in the rotary photoelectric encoder of storehouse Bole on the isolating switch rotation axis, when confirming that isolating switch is failure to actuate, pull shaft encoder with external force, isolating switch rotation axis and storehouse Bole's shaft room do not have relative motion.
3. power on, insert monitoring terminal.On the terminal, key in test command, observe the run-length data of shaft encoder, this moment, run-length data was zero.Close test command, outage.
4. normal operation powers on.The device with server between be connected through fiber optic Ethernet, upload the run-length data of sampling.
