Description
Technical field
The present invention relates to transformer equipment field, more particularly to a kind of state access controller.
Background technology
In existing substation, more set monitoring systems are usually mounted with, these monitoring systems come from different manufacturers, are used for
Different environmental variances is monitored, such as to transformer/reactor, capacitance type equipment, metal oxide arrester, open circuit/GIS etc.
Equipment obtains corresponding monitoring data.This kind of monitoring data will first pass through state access controller (Condition
Acquisition Controller, CAC), state access gateway (Condition can be just sent to after being detached in CAC
Acquisition Gateway, CAG).CAC is installed on the station level of substation, the fortune for the monitoring system to substation
Row control and all transformer equipment status datas collect storage and forwarding.
For example, the transformer equipment state access controller described in the patent document of Publication No. CN203101932U
(power transformation CAC), it is connected with comprehensive monitoring unit in intelligent substation or the IED for possessing comprehensive monitoring Elementary Function by I1 interfaces
Connect；Transformer equipment state access controller accesses net provincial company end power transformation CAG by I2 interfaces, realizes connecing for power transformation status information
Enter, achieve the purpose that transformer equipment status information is managed collectively.This kind of state access controller have perfect data analysis and
Diagnostic function, early warning is carried out while master status information is provided to the failure that may occur；Equipment health status is done
Go out estimation.For avoiding power equipment accident from occurring, ensureing equipment safety, reliable, normal operation has great significance.
Since CAC plays the role of the forwarding and storage of data between monitor and CAG, and monitor is usually covers more
, therefore, CAC is equipped with multiple interfaces, for accessing different monitor and communication equipment, for example, ethernet communication connects
Mouth, fiber optic data communication interface, serial line interface, USB interface etc., the monitor species that these interfaces access as needed are fixedly mounted
On the baffle of mono- side of CAC.Since the usual number of the monitor of access is more, and interface is more intensive on baffle, because
This, even if incoming end is engaged by micro deformation with interface, but issuable interference is still between different incoming ends
The loosening of incoming end is be easy to cause, in this case, how to keep consolidating connection between each incoming end and interface, is desirable
Solve the problems, such as.
In addition, when adding new monitor or replacing with the monitor of distinct interface, the interface of the fixation on baffle
It can not just may be adapted to, and merely because interface mismatch just replaces whole CAC and will result in waste.If can be by CAC's
Interface is replaced, and without significantly changing main circuit, then can realize being adjusted flexibly for monitor in substation.
The content of the invention
In order to solve the problems, such as that the monitor terminals of CAC are not firm enough, the present invention provides a kind of access of state to control
Device, can reinforce the cooperation between each terminals and interface when multiple monitor circuits access.
A kind of state access controller, including circuit main board, house the circuit main board and the babinet of a side opening and
Some interfaces coordinated with monitor terminals, the babinet have the baffle for being used for sealing the opening, each interface installation
On the baffle, the state access controller is additionally provided with some pinch plates for being coated on and being used for spacing terminals on interface,
Each pinch plate one end is rotatably assorted with the casing top, and the other end is engaged by clamping with the bottom of box.
Interface on state access controller includes：It is ethernet interface, fiber optic data communication interface, USB interfaces, serial
Communication interface.When being terminals configuration in spite of some interfaces, separately ensure to be fitted close between the two by screw-tightened,
But this fixed form result in the workload coordinated between terminals and interface, and most of the time, terminals are only
To be engaged by the micro deformation of some elastomeric elements with interface, this access way when wiring is excessive, easily because
Interference causes to loosen between wiring.On the state access controller of the present invention, access after each monitor terminals, by card
Buckle tumble card is connected to the bottom of state access controller, and pinch plate envelopes interface, so as to by terminals pressure in the interface, prevent
Only since different wiring access the wiring loosening caused by excessively intensive interface causes to interfere with each other.
In order to protect the connection between wiring and terminals not cause to damage because of the extruding of pinch plate, as a kind of excellent
Choosing, the position corresponding to interface on pinch plate are equipped with the through hole for wearing monitor wiring.Wherein the width of through hole is less than wiring
The width at end and it is greater than or equal to line-widths.
Due to terminals in volume it is bigger than wiring, in order to enable wiring by while ensureing that pinch plate can be with
Terminals are against without making terminals pass through among the through hole, as a preferred embodiment, the through hole extends to the pinch plate
With one end of bottom of box clamping.
As another preferred embodiment, the pinch plate is made of elastic material.Elastic material is, for example, metal clips or rubber
Glue etc., micro deformation occurs when terminals pass through through hole so that terminals can be pierced by from the through hole other end, and can be in wiring
End is recovered after being pierced by, to ensure terminals being pressed on the interface.
Furthermore, one end that the pinch plate coordinates with the casing top is fixed with shaft, the casing top
With groove, position corresponding with shaft both ends is equipped with limited block in groove, between the limited block and groove floor
The space for being used for housing the shaft is formed, is additionally provided with the groove：
Sliding block, is resisted against in the shaft；
Spring, the sliding block is pressed in the shaft.
This mode of being rotatably assorted is conducive to the installation and dismounting of pinch plate, is only needed cunning when needing and dismantling pinch plate
Block is lifted up, and shaft is taken out from groove, easy to the replacement of pinch plate；At the same time, also ensure that pinch plate is working
When be maintained in groove and will not loosen abjection.Spring may bend to other directions during pushing, cause sliding block
Depart from groove, to avoid such case from occurring, it is necessary to spacing to spring progress, preferably, spring pocket is arranged on push rod, and is pushed away
Bar one end is fixed on sliding block, and the other end is stretched into the guide groove in recess sidewall.
In order to make the cooperation between shaft and sliding block more smooth, as a preferred embodiment, the sliding block and shaft against
Side upper end is equipped with rounding.
Furthermore, the bottom of the babinet has locating slot, and corresponding position is equipped with and institute on the pinch plate
The fixture block of locating slot clamping engagement is stated, the cross section of the fixture block is triangle.Triangular in shape easily slide into fixture block cross section is determined
It is engaged by clamping in the groove of position with locating slot.
When opening pinch plate progress wiring, in order to facilitate force so that fixture block is separated with locating slot, as a preferred embodiment,
The pinch plate has force application board backwards to the side wall of the fixture block.
Substation causes existing interface can not be with new monitor for that may increase monitor or renewal monitor in the later stage
Terminals match, in order to make state access controller can adapt to different monitors, as a preferred embodiment, the interface is removable
Unload and be connected on the baffle, connected between interface and circuit main board by plug connector.
State access controller of the present invention can increase what is connected between terminals and interface when accessing multiple monitors
Stability, prevents from gradually loosening between the two, reduces unnecessary maintenance.
