Description
Technical field
The utility model relates to a kind of conductor rail, and especially for the conductor rail of middle pressure and low pressure range, described conductor rail has at least two conductors and at least one insulator between described conductor, has conductive layer in described insulator inside.
Background technology
Conductor rail, be also referred to as bus or as conductor rail, for example, in switch cubicle and in infrastructure, obtain extensive use.Particularly, within the scope of middle pressure, conductor rail often uses at rectifier and for controlling between the inverter of large-size machine.Because conductor rail great majority use this conductor and insulator therein by particle deposition, as the region of dust, oil and moisture contamination in, therefore there is the danger of leakage current.This leakage current can mean obvious danger.The strong electric field that first leakage current mainly by the dust deposit on insulator, particularly passes through between the conductor of conductor rail produces.Can for example make the single region of staubosphere become dry by leakage current.This region may have high electric field strength so.Result can be controllably do not discharge with therefore damage element-with therefore expensive upkeep cost-and electricapparatus damage of being connected.
The insulator nowadays therein with conductive layer has obtained application in high pressure technique.But single conductive layer is not to contact, and surrounds completely but be insulated material.
DE 28 33 036 B1 have described a kind of for voltage measuring apparatus gas or fluid insulation, that have the high-tension distribution equipment of the high-pressure conductor of the metal shell that is arranged in ground connection, and this voltage measuring apparatus comprises and is placed in voltage divider in metal shell, that have voltage tap.
US 4 401 844 A have described a kind of conductor rail, and wherein this conductor rail has low especially inductance.This conductor rail mainly comprises that two by the separated conductor of insulating material.
Utility model content
The purpose of this utility model is, reduces the lip-deep leakage current of the insulator in conductor rail by improved insulating properties.
This object realizes by a kind of conductor rail, it is especially for the conductor rail of middle pressure and low pressure range, described conductor rail has at least two conductors and at least one insulator between described conductor, there is conductive layer in described insulator inside, it is characterized in that, described conductive layer stretches out at least in part from described insulator, described conductive layer mutually and/or cross resistance with described conductor dbus and/or capacitor is connected, described conductor rail has the interface for measurement mechanism, described measurement mechanism be designed for control between described conductive layer or described conductive layer and the electric current between any in conductor described in these, charge difference and/or voltage, and the measurement result of described measurement mechanism and rated value comparison, and trigger alarm signal is set in the time exceeding described rated value.
This object also realizes by a kind of method for the manufacture of this conductor rail.
Conductive layer can place conductive layer by overlapping each other and insulator forms like this, inserts respectively a conductive layer between two insulators.Can realize stable connection by bonding each layer or by casting technique.This outer conducting layer or can there is identical dimensions except comprising the contact of insulator, or can from insulator, stretch out partly.In addition each plate can be by being connected to each other by the circuit of resistance and capacitor.There is multiple combination possibility at this: first conductive layer connects by resistance and/or capacitor respectively.In addition each conductive layer is connected on ground wire or housing by resistance and/or capacitor.The conductive layer connecting so also can also be connected with in conductor one by resistance and/or capacitor.This layout realizes the lip-deep and inner electric field that is reduced in insulator.Only otherwise exist and being connected of in conductor one, electric field is in the conductively-closed of the inside of two conductive layers.The electromotive force of each conductive layer can regulate by the connection via (high ohm) resistance of conductive layer.Definite electromotive force on this each conductive layer being positioned between conductor allows electric field effectively to change.Reduce to reduce the surperficial leakage current at insulator by the electric field that may exist partly.If conductive layer is connected with ground wire, thereby arrives conductor and may damage like this before conductor rail causes controllably not discharging at leakage current so, can derive contingent leakage current.If be added in the voltage temporal evolution on the conductor of conductor rail, each conductive layer and/or conductor dbus are crossed being connected to each other of capacitor and are applicable to so.When this is particularly suitable for having interference signal, at this also referred to as stray electrical current.And capacitor may be necessary or can connect and be introduced into for control circuit on one's own initiative for measuring process described below.
A kind of method is suitable for manufacturing for packing the new insulator of conductor rail into.In addition be particularly suitable for the expansion of conductor rail according to this method, in this conductor rail, had conductive layer in insulator inside.These conductive layers can be for example made and can be contacted by cut.In addition also can replace existing insulator with a kind of insulator with conductive layer.Then can realize the connection of electronic unit, for example resistance.And this external enwergy of insert of insulator with conductive layer is integrated in existing manufacture process in simple mode.Then realize the connection of conductor and/or conductor layer.Thisly can realize replacing insulator in the situation that in common maintenance work for the method that installs existing conductor rail additional.In the time manufacturing new conductor rail, substantially without the manufacture method that changes conductor rail, this is to change because of only having insulator.As situation may, necessary optional feature can be integrated as resistance or measurement mechanism after manufacturing.
In a favourable execution mode, conductor dbus is crossed the resistance being connected in series and is connected, and between two resistance being connected in series, has respectively the connection of conductive layer.This execution mode is similar to uncharge voltage divider and works, to make to determine by resistance value the electromotive force of each conductive layer.The danger that the part that makes by this way field intensity can adjust leakage current occurs.Therefore particle only still causes leakage current with the degree reducing in surperficial deposition.In addition,, if the trend of leakage current is crossing with the conductive layer of contact insulator surface, this leakage current is stopped on it is orthogonal to the direction of propagation of conductor extension so.But keep noting, the resistance value between conductor must be so high, so that the power loss that must occur is not damaged resistance.Therefore can be from hundreds of megohm at least until select resistance value in the number range of begohm scope.If only have conductive layer and/or ground wire to be connected, resistance value also can be less.As situation possibility, can consider ACTIVE CONTROL resistance, to optimally formulate resistance value.
In another favourable execution mode, all resistance has identical resistance value, and conductive layer has each other equidistant spacing and has equidistant spacing with conductor.If all resistance between conductor and conductive layer have identical resistance value, the summation minimum of electrical potential difference between conductor and conductive layer so.In the time that conductive component, conductor and the spacing that is arranged in the conductive layer between conductor are respectively equidistant, and in the time that resistance value is identical, the electric field of appearance is lowered to minimum value.Utilize in this embodiment minimizing of electric field not only to reduce leakage current, and reduced the trend of controllably not discharging.
In another favourable execution mode, the coating of the conduction that resistive arrangement is insulator, for example polymer of conduction.If there is contact between conductive layer and the coating of conduction, the surperficial coating of insulator is corresponding to the foregoing circuit of voltage divider so.But the coating of conduction needn't contact conductive layer.This can for example realize by the groove of the coating interface around conductive layer, conduction and the conductive layer being surrounded completely by insulator in addition.Enough in most applications, only apply not by the local surface covering of conductor.Therefore the coating of conduction can for example be made up of plastics or paint, wherein embeds and has nanocrystal, for example aluminium bunch.Can use equally the plastics of conduction, its polymer has pi-conjugated electric structure.Aspect coating, notice, the resistance value between conductor is at least in begohm scope (～10^9Ohm).Except the current potential of compensation on conductive plate and conductor, the coating of the conduction of coating is for example by changing layer thickness for being directly controlled at the lip-deep field intensity of insulator.In addition can stop the leakage current that may occur by the coating of conduction, this is because the little resistance of ratio stratum granulosum based on coating is derived the electric current occurring by the coating of conduction.Therefore can effectively reduce local exsiccation, and reduce significantly not the controllably danger of electric discharge thus.
In another favourable execution mode, equipment has the interface for measurement mechanism, wherein measurement mechanism be designed for control between conductive layer or conductive layer and ground wire between electric current, charge difference and/or voltage.Except controlling electric field, the leakage current that may occur between conductor and/or conductive layer can detect by the interface of measurement mechanism.Additionally, can determine the electric charge on conductive layer.Measurement result can obtain with the time interval of rule.The best maintenance shop that can for example measure by this method conductor rail every.
In another favourable execution mode, propose measurement result and rated value comparison.In the time of overrate, realize and trigger predetermined event, for example alarm signal.The result of the measuring process of introducing above not only can with definite rated value comparison, and additionally also can record the variation in time of each parameter, parameter is for example resistance value between conductor and/or conductive layer or the electrical potential difference between conductive layer.In the time exceeding the determined value of measured value and/or its and change, can for example infer pollution.By signal, for example flash near the signal lamp of conductor rail or automatically information generated can realize optics control.Activate in addition for the existing system of purification receiving rail-engaging-and/or interrupt the voltage supply to conductor rail, to do not damage the electronic equipment of connection.
In another favourable execution mode, the leakage current on the outside of insulator is designed for to measurement mechanism and powers.The outside voltage supply of measuring process, it can not guarantee to prevent fault for example for operational amplifier.In addition until particle deposition causes disturbing the time interval of conductor rail very long in normal circumstances.Can for example realize measuring process by the light-emitting diode being connected with conductor rail via capacitor.Electric current flows between two plates, so the variation in time of the electrical potential difference of realization between conductive layer.Change in voltage between conductive layer causes the electric current by capacitor, and therefore causes light-emitting diode to flash.This light for example passes through optical conductor guide probe, this detector trigger alarm signal.
In another favourable execution mode, resistance value and/or electric capacity are correspondingly adjusted demand by active circuits.Active circuits is for resistance or the electric capacity of adjustment component, and these parts are connected with conductor and/or conductive layer.Therefore can adopt the consideration on current application conditions.
