Description
Technical field
The present invention relates to substation equipment state monitor technology field, particularly to a kind of status monitoring terminal structure for electic protection pressing plate.
Background technology
Electic protection pressing plate (also referred to as electic protection connection sheet) forms the visuality of junction point and cut-off point after operating because of it and obtains most commonly used application in domestic protection device.At present; the power plant put into operation, protection screen of transformer substation are fitted with large number of electic protection pressing plate; owing to having cut-off point intuitively, operations staff may determine that protective relaying device circuit state in which, provides great convenience for maintenance, operation.According to the difference of access protection device secondary circuit position, electic protection pressing plate can be divided into defencive function pressing plate and the big class of output clamping two.Defencive function pressing plate achieves some function of protection device, such as the throwing, retreating function of main protection, distance protection, zero-sequenceprotection etc., can be used for changing the control model of protection.Output clamping determines the result of protection act, and the object according to protection act outlet effect is different, can be divided into tripping operation output clamping and start pressing plate.Tripping operation output clamping directly acts on this switch or other switches jumped by connection, if tripping operation output clamping is thrown in leakage, even if protection device correct operation, also cannot tripping switch to excise fault；Start pressing plate to open into being used as other protections.
The structure of common electic protection pressing plate as depicted in figs. 1 and 2, is mainly the insulating base 1 of strip by entirety, is plugged on two connection terminals 2 at insulating base both ends and constitutes in order to connect two connecting plates 3 connecting terminal.Two bottoms connecting terminal 2 pass below insulating base 1, in order to be connected in protection circuit, by adjusting the connecting plate 3 inputs between two connection terminals 2, exiting state, control the conducting of protection circuit, disconnection；Wherein, electic protection pressing plate is under input state, and its connecting plate 3 connects terminal 2 with two relative location status connecting terminal 2 as it is shown in figure 1, connecting plate 3 connects conducting two；Electic protection pressing plate under exiting state, its connecting plate 3 with two relative location status connecting terminals 2 as in figure 2 it is shown, connecting plate 3 is connected terminal 2 with one of them disconnects so that two connection terminals formation open circuits.Two upper ends connecting terminals 2 have been threaded connection insulation knob 4, by screwing insulation knob 4, can be pressed on by connecting plate 3 on connection terminal 2, with the input of fixed connecting plate, exit state.

Owing to the installation site of electic protection pressing plate is the most relatively low and quantity is more, arrangement comparatively dense; and the throwing of electic protection pressing plate move back must be by manual operation; check on by the responsibility of operations staff, actual techniques level completely; so being easy to occur patrolling and examining slip and operation mistake; especially after Unattended substation, the throwing of electic protection pressing plate is moved back mistake and is more difficult to find in time.In actual motion, moving back improper because electic protection pressing plate is thrown, cause protection system the phenomenon of correct operation not happen occasionally, electic protection pressing plate is thrown and is moved back mistake and once occur, then can cause protective relaying maloperation or tripping, and its consequence is hardly imaginable.
Therefore; in order to more effectively the throwing state of moving back of electic protection pressing plate be monitored; the most a lot of power plant, transformer station begin to use electic protection pressing plate remote-end monitoring system; realize electic protection pressing plate being put into, exiting the remote monitoring of state; so that finding that the situation moving back mistake thrown by electic protection pressing plate in time, thus actively take counter-measure.
So-called electic protection pressing plate remote-end monitoring system, it is common that install status monitoring terminal on electic protection pressing plate additional, far-end is then by monitoring that computer and status monitoring terminal carry out radio communication.Monitoring signal wireless transmitter it is provided with in status monitoring terminal; during its work, external wireless transmission electic protection pressing plate puts into status information; the duty monitoring signal wireless transmitter in status monitoring terminal is set by manual operation, controls whether that sending electic protection pressing plate puts into status information；If monitoring that computer receives the electic protection pressing plate input status information that status monitoring terminal is sent; then represent that corresponding electic protection pressing plate is in input state; otherwise; if monitoring that computer receives the electic protection pressing plate input status information that this status monitoring terminal is sent, then it represents that corresponding electic protection pressing plate is in the state of exiting.
But, the design of existing status monitoring terminal structure is relatively simple, the duty of its monitoring signal wireless transmitter is generally set by the throwing, retreating of a knife switch, and easily there is the situation of loose contact in life-time service back switch blade switch, and the objects such as circuit around, device are encountered knife switch and are the most easily caused the throwing, retreating state of knife switch to change so that status monitoring terminal works less stable by mistake.Additionally, status monitoring terminal is the most directly directly installed on electic protection pressing plate by screw, inconvenience is not only installed, and electic protection pressing plate and relevant connection circuit may be caused damage by Rig up error.On the other hand; owing to the throwing of electic protection pressing plate being moved back operation and the duty of status monitoring terminal is arranged operation depending on manual operation and complete; it is therefore possible to occur because manual operation error causes the duty of status monitoring terminal to move back, with the throwing of electic protection pressing plate, the situation that state is the most corresponding, that causes far-end monitors that the throwing of electic protection pressing plate is moved back status monitoring information and made a mistake by computer.These factors all directly affects use operation ease and the job stability of status monitoring terminal.

Detailed description of the invention
The invention provides a kind of status monitoring terminal structure for electic protection pressing plate.Fig. 3 shows a kind of schematic diagram being embodied as structure of status monitoring terminal of the present invention.As it is shown on figure 3, this status monitoring terminal has an overall elongated terminal shell 10, this terminal shell 10 has a mounting structure so that it can be mounted in parallel the side of the insulating base at electic protection pressing plate.The middle part of the terminal shell 10 of strip has that one is vertically arranged and opening is positioned at the guide chute 14 of terminal shell upper surface, this guide chute 14 is inserted into a sliding bar 20 that vertically can slide up and down along guide chute, and the upper end of sliding bar 20 is stretched out from the opening of guide chute 14.The upper end of sliding bar 20 is fixedly installed the lever 30 of isolation material.And the partial structurtes coordinated between guide chute with sliding bar are as shown in Figure 4, the bottom of sliding bar 20 has the installing hole 21 of a lateral direction penetrating, installing hole 21 is equipped with along the arrangement of through direction the ball 22 of two conductive material, and between two balls 22, is crimped with the spring 23 of a conductive material；And have between guide chute 14 and sliding bar 20 and can slide up and down the position limiting structure of scope by limit slippage bar, it is equipped with spherical groove 15 when being simultaneously directed on the inwall of chute 14 slide into upper limit position corresponding to sliding bar at two ball 22 positions and when sliding into lower position at two ball 22 positions, and when sliding into lower position corresponding to sliding bar, the groove inner wall of two spherical grooves 15 at two ball 22 positions is equipped with the electric conduction electrode-plate 43 of mating shapes respectively.Additionally, be also equipped with in terminal shell 10 monitoring signal transmission circuit；The circuit structure principle schematic of this monitoring signal transmission circuit is as shown in Figure 5; including independent current source 41; and after powering by this independent current source 41 and be energized can externally wireless transmission electic protection pressing plate put into status information monitoring signal wireless transmitter 42, two electric conduction electrode-plates 43 in guide chute then as disconnect two contact terminals be connected electrically in monitoring signal wireless transmitter 43 current supply circuit in.
Use the status monitoring terminal of said structure, when the sliding bar inserted in guide chute slides into upper limit position or lower position, two balls that sliding bar bottom is placed in installing hole will be ejected because suppressing by spring, it is embedded in the spherical groove on guide chute inwall, wherein, when sliding bar slides into lower position, due to spring eject two balls with respectively with the electric conduction electrode-plate joint in two spherical grooves, i.e. by the spring of conductive material and two balls two electric conduction electrode-plates are defined and conduct, the current supply circuit monitoring signal wireless transmitter is made to form path, monitoring signal wireless transmitter energising, just externally wireless transmission electic protection pressing plate puts into status information；And when sliding bar leave lower position, ball deviate from from two spherical grooves being equipped with electric conduction electrode-plate time; the electrical connection of two electric conduction electrode-plates disconnects; the current supply circuit monitoring signal wireless transmitter is made to form open circuit; monitoring signal wireless transmitter quits work, and no longer externally wireless transmission electic protection pressing plate puts into status information；Thus, just can adjust the sliding bar position that slides up and down in guide chute by holding operation handle and the duty of status monitoring terminal is set, easy and simple to handle.Simultaneously, ball owing to being gone out by spring suppression on sliding bar defines location to sliding bar when being embedded in spherical groove, limit slippage bar the most freely slides up and down, must rely on and press or pull up sliding bar under certain external force and make ball deviate from from spherical groove, sliding bar can be again made to slide, thus decrease the situation generation changing status monitoring terminal operating status because surrounding objects encounters sliding bar by mistake, the lever of sliding bar upper end is isolation material, it also avoid the circuit of surrounding, when the objects such as device contact with lever, the duty on monitoring signal transmission circuit produces impact；And when sliding bar slides into lower position, suppress under active force at spring, two balls can keep being in close contact with two electric conduction electrode-plates all the time, it is not easy the situation that poor electric contact occurs, it is possible to keep the current supply circuit of monitoring signal wireless transmitter to be in stable conducting state well；Status monitoring terminal works stability is so made to be greatly improved.As can be seen here, the status monitoring terminal structure that the present invention is directed to electic protection pressing plate is improved by structure, solves status monitoring terminal works less stable in prior art well, uses unhandy problem.
In the status monitoring terminal structure of the present invention, for terminal shell is mounted in parallel at the mounting structure of the insulating base side of electic protection pressing plate, the mounting structure that can take various forms when specific design, application.But as one more preferably organization plan, as shown in Figure 3, can be made up of the housing our department 11 that can mutually fasten and housing engaging portion 12 with design terminal housing 10, and housing our department 11 and housing engaging portion 12 respectively have a clamping limb extended laterally outward 13 on the sidewall install electic protection pressing plate side, and housing our department 11 and housing engaging portion 12 latter two clamping limb 13 that is interlocked can enclose the holding tank forming the insulating base mating shapes with electic protection pressing plate, so that terminal shell 10 can be interlocked by housing our department and housing engaging portion and be clamped the side of the insulating base being arranged on electic protection pressing plate concurrently, as shown in Figure 6.Since so; utilize the structure that housing our department 11 and housing engaging portion 12 are interlockingly connected; just status monitoring terminal can be clamped easily on the insulating base 1 being arranged on already installed electic protection pressing plate; and the structure of electic protection pressing plate will not be destroyed, it is possible to the preferably installation operation for status monitoring terminal offers convenience.According to such mounting structure scheme, guide chute, sliding bar and monitoring signal transmission circuit in status monitoring terminal are preferably both arranged at housing our department, to avoid using Split type electric line structure, the hidden danger that the design difficulty that can reduce Split type electric line structure, the connecting portion electrical contact avoiding Split type electric line structure to bring are bad, it is simultaneously also beneficial to realize the integrated of structure and circuit, reduce production cost, offer convenience for producing.
Equally, in status monitoring terminal structure, position limiting structure between guide chute and sliding bar can also take various forms.But as a kind of preferably design, position limiting structure can be designed as: as shown in Figure 4, stopper slot 24 it is provided with along its length on sliding bar 20, the opening part of guide chute 14 is provided with spacing preiection 16, this spacing preiection 16 embeds in described stopper slot 24, the scope that limit slippage bar 20 slides up and down along guide chute 14.It is relatively simple that the advantage so designed is mainly structure, it is simple to generates processing and assembles；Simultaneously, this position limiting structure also plays the effect that limit slippage bar rotates in a circumferential direction, enable to the corresponding relation that ball on sliding bar and the spherical groove on guide chute inwall keep fixing in orientation, it is to avoid when sliding bar slides into upper limit position or lower line position, cause ball cannot embed the problem that spherical groove realizes positioning because the orientation of ball Yu spherical groove staggers.
As the further improvement project of one, as shown in Figure 3, the sliding bar 20 of status monitoring terminal of the present invention can increase cue mark 25 is set, this cue mark 25 arranges position on sliding bar, making when sliding bar 20 slides into lower position, cue mark on sliding bar 25 is placed in guide chute 14 just completely near the position of opening.So, when sliding bar slides into lower position, now the current supply circuit of monitoring signal wireless transmitter is conducting, simultaneously because cue mark is hidden in guide chute the position near opening, from seeing the cue mark sliding bar in appearance；As long as and sliding bar slides at lower position slightly upward again, the ball of sliding bar bottom can be deviate from from two spherical grooves being equipped with electric conduction electrode-plate, now the current supply circuit of monitoring signal wireless transmitter is open circuit, and meanwhile, rising along with sliding bar, cue mark on sliding bar the most correspondingly can expose at the aperture position of guide chute, therefore from the most just it can be seen that cue mark sliding bar.Thus; operator just can be intuitively by checking that the cue mark on sliding bar judges the duty of status monitoring terminal; know with the throwing of electic protection pressing plate, the duty of status monitoring terminal moves back whether state exists the most corresponding situation, it is simple to operator check that fault and duty arrange the situation of mistake.And the concrete form of cue mark on sliding bar, can be to be color lump, character of being marked on sliding bar by modes such as spraying, etchings etc..
nullIn addition，As further improvement project on the other hand，As shown in Figure 3，In the status monitoring terminal of the present invention，The strip that the lever 30 on its sliding bar generally extends laterally outward can be designed from sliding bar 20 upper end，Its horizontal expansion direction is perpendicular to the length direction of terminal shell 10 and towards the side installing electic protection pressing plate，And the length of lever 30 horizontal expansion of this strip，When making the side of insulating base 1 that terminal shell 10 is arranged on electic protection pressing plate，When sliding bar 20 slides into upper limit position，Lever 30 can connect between terminal and contour with connecting plate 3 position (as shown in Figure 6) the two of electic protection pressing plate away from the end connecting sliding bar side，And when sliding bar 20 slides into lower position，The connecting plate 3 putting into conducting two connection terminal on electic protection pressing plate is just pressed on the lever 30 upper surface (as shown in Figure 7) away from the end connecting sliding bar side.nullSince so，When the side of the insulating base that the status monitoring terminal of the present invention is arranged on electic protection pressing plate，If being set to exit state by the connecting plate of electic protection pressing plate，And the sliding bar of status monitoring terminal is slid into upper limit position，As shown in Figure 6，Owing to lever is away from connecting the end of sliding bar side between two of electic protection pressing plate connection terminals and contour with connecting plate position，Connecting plate is put into connection two connection terminals and defines stop，It is thus possible to prevent electic protection pressing plate from the state that exits miscarried into，The current supply circuit the most now monitoring signal wireless transmitter in status monitoring terminal is in off state，Will not externally send electic protection pressing plate and put into status information，Therefore，Now the duty of status monitoring terminal is corresponding with the state that exits residing for electic protection pressing plate；nullAnd if the sliding bar of status monitoring terminal being slid into lower position，And be set to put into connection status by the connecting plate of electic protection pressing plate，As shown in Figure 7，It is in channel status owing to now status monitoring terminal being monitored the current supply circuit of signal wireless transmitter，Can externally send electic protection pressing plate and put into status information，It is simultaneously connected with plate and is just pressed on the lever upper surface away from the end connecting sliding bar side，The sliding bar upward sliding of status monitoring terminal is defined stop，It is thus possible to prevent the current supply circuit monitoring signal wireless transmitter in status monitoring terminal from disconnecting because of sliding bar upward sliding，Therefore，Now the duty of status monitoring terminal is also corresponding with the input connection status residing for electic protection pressing plate，Only the connecting plate of electic protection pressing plate is switched to the state of exiting again，Side can the sliding bar of upward sliding status monitoring terminal.Thus, the duty that just can allow status monitoring terminal is moved back state and is preferably kept corresponding with the throwing of electic protection pressing plate, it is to avoid that causes far-end monitors that the throwing of electic protection pressing plate is moved back status monitoring information and made a mistake by computer.
nullIn sum，The present invention is directed to the status monitoring terminal structure of electic protection pressing plate，It can be conveniently mounted to the side of insulating base of electic protection pressing plate，And the duty of status monitoring terminal can be set by the holding operation handle adjustment sliding bar position that slides up and down in guide chute，Install and use easy to operate，And fit structure makes status monitoring terminal works stability be greatly improved between its guide chute and sliding bar，Additionally can optimize design by many，The duty allowing status monitoring terminal is moved back state and is preferably kept corresponding with the throwing of electic protection pressing plate，Avoid the supervision computer causing far-end that the throwing of electic protection pressing plate is moved back status monitoring information to make a mistake，Check that fault and duty arrange mistake and provide convenience for operator，Solve status monitoring terminal works less stable in prior art well，Install、Use unhandy problem.
Finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent, without deviating from objective and the scope of technical solution of the present invention, it all should be contained in the middle of scope of the presently claimed invention.
