Definitions

  • the invention relates to a method for displaying device parameter values on industrial switching devices, in which the setting of the switching device parameters can be carried out by means of remote control and which additionally have devices with which these parameter values can be read directly on the switching device. Furthermore, the invention relates to a device for carrying out the method according to the invention.
  • switching device parameters are transmitted directly to the switching device, e.g. adjusted via potentiometer or tap changer.
  • Such switching devices are well known and available from many manufacturers. If such a switching device is combined with an electronic module with which these switching device parameters can be changed by remote adjustment, there may be differences between the actual setting of these parameters and the parameter values readable on the device itself.
  • circuit breakers increasingly have a communication interface via which the currently set device parameter values can also be overwritten.
  • the values may only be changed in such a way that an unsafe condition is not possible, ie, for example, an overcurrent setting can only be reduced compared with the values that can be read on the switching device itself. This ensures in the devices of the prior art that the switching device triggers in any case at the latest when reaching the readable on the device limit.
  • the display showed the setpoint value of a device parameter transmitted by the remote setting, it could happen that the value is displayed faster than it is set in the setting device when changing the setpoint value due to the speed of electronic displays. In particular, this risk is given when combining the electromechanical adjustment of a parameter with an electronic display. It is also conceivable that the adjuster fails. In this case, the new setting value may be shown on the display while the device setting has not changed from the original setting. If the new setpoint is remotely set to a value higher than the old one, then in these cases, an inadmissible, unsafe operating condition would occur until the setting of the unit is as shown on the display.
  • the object of the invention is to specify a method for ensuring the conformity of a currently set parameter value of an industrial switchgear with the display of this value on the device itself, wherein the switchgear parameter is adjustable by means of an adjustment on the device itself and additionally via remote adjustment, and wherein the display of the parameter value through a separate display.
  • the invention is based on the object to provide a device for carrying out the method.
  • the invention proposes to read the parameter value to be displayed on the display from the setting device of the device.
  • the adjusting device has for this purpose a device for reading the set value.
  • the transmission of the parameter value from the setting device to the display can take place with a constant frequency, as well as a single message only if the parameter value is changed.
  • the invention proposes, when setting a switching device parameter via an electromechanical device, to provide a servomotor to the setting device of the switching device parameter on the device itself, which is actuated during the remote adjustment of the corresponding parameter value and accordingly adjusts the setting device.
  • the switching device may of course have more than one adjustment of switching device parameters, of which one or more of these devices according to the invention may be equipped with a servomotor. It is also conceivable that only one or more parameters are implemented remotely adjustable on a switching device, with other parameters are adjustable only on the device itself.
  • the invention relates to all possible combinations of remotely adjustable and only on the device self-adjustable switchgear parameters as well as the tracking and display of these parameter values.
  • the servomotor consists of a micro or nano-engine. Since such motors are very small, their use is particularly suitable for switches with several parameters to be set, in which so several adjustment for switching device parameters on the device itself eg in the form of tap changers or potentiometers are available.
  • PCB motors as servomotors.
  • These are piezomotors that can be integrated directly into a printed circuit board.
  • piezo motors of this kind piezoelectric components which, upon application of a suitable electrical voltage, perform mechanical oscillations are coupled to a resonator, which in turn rests against a movable element.
  • the resonator converts the oscillations of the piezoelectric component into preferably elliptical oscillations of the contact area of the resonator with a rotor.
  • the movable member preferably moves in a first direction when a first voltage is applied to the piezoelectric device in a first direction, when a second voltage is applied at a second frequency to the piezoelectric device in a preferably opposite second direction.
  • a PCB motor can perform the adjustment of the adjustment of the switching device parameter without an additional gear.
  • connection of a PCB motor with the adjusting device of a switchgear parameter is realized on the device itself by means of a slip clutch.
  • Fig. 1 is a block diagram for interconnecting a Ferneinstellvoroplasty 1 for setting the Weg Benöparamater an industrial switchgear with the setting device 20 for the switchgear parameters on the device itself and the display 15.
  • switchgear parameters can be, for example, thresholds for overload or a short-circuit current release and can either via the Ferneinstellvortechnisch 1 on the industrial switchgear are transmitted, or set directly on site at the adjuster 20, usually using a manual adjustment aid 5 such as a screwdriver.
  • the setting acts directly on the setting device 20.
  • the value of the parameter for the display in the display 15 is read out of the setting device 20 and transmitted to the display 15.
  • the setting device 20 has a device for reading out values.
  • This device may be an integral part of the adjustment device 20.
  • the value can only be read out once with a value change or with a certain frequency.
  • the frequency can be selected so that a reading is substantially continuous and is forwarded to the display 15, so that the change in value is traceable on the display 15.
  • Fig. 2 the front panel 10 is shown with the adjustment field for a switchgear parameters of an electrical switching device.
  • a screwdriver which can be inserted into a slot 25 of the adjusting knob 21, the adjusting knob 21 can be rotated, thereby changing values for a switchgear parameter.
  • a display 15 is shown, on which the parameter value currently set on the setting device 20 can be read.
  • Fig. 3 is a schematic diagram of a device for tracking a trim potentiometer or a switch for setting a switchgear parameter by means of a PCB motor in section. While the current setting value can be read directly on the display 15 when setting a switchgear parameter by means of the adjusting knob 21 directly on the device, this can be done remotely Setting value for devices according to the prior art, the set value of the position of the adjustment knob 21 and the actual device setting differ. In the inventive device according to Fig. 3 is adjusted at a remote setting of a new setting value, the existing position of the knob 21 to the new value. The parameter value for display on the display 15 is read from the setting device 20.
  • a further circuit board 40 for the motor plane is provided, which is equipped with electrical piezo elements 50, 60 on both sides.
  • the piezoelectric elements 50 of a first, the front panel 10 of the switch side facing act on a first rotor plate 22 on the knob 21 and serve to track the knob 21 in a remote adjustment of the parameter value.
  • the piezoelements 60 of the second side facing away from the front panel 10 of the switch act on a setting of a trim potentiometer 80, which in turn acts on components on a further printed circuit board 100 for the switching device parameter electronics.
  • the second rotor plate 70 has a mechanical interface 75 to the trimming potentiometer.
  • the adjusting knob 21 is connected via retaining lugs 28 with the second rotor plate 70 so that both rotor plates 22, 70 are pressed against the electrical piezo elements.
  • the knob 21 and the second rotor plate 70 together form the rotor of the motor.
  • the piezo elements 50, 60 are firmly connected to the printed circuit board 40.
  • the friction is sufficient by the pressing force, which is generated by the retaining lugs 28, the first rotor plate 22 and the second rotor plate 70 from.
  • the PCB motor is driven by the electronics of the switching device 100 via a motor driver until the setting switch or the setting potentiometer 80 corresponds to the new value.
  • This is read out in a first variant of the setting device 20 and forwarded to the display 15, and is then readable locally on the device.
  • a second variant of the set value with a certain frequency substantially continuously read from the setting device 20 and forwarded to the display 15, so that the adjustment process can be followed on the display 15.
  • the display can be designed as an e-paper.
  • e-paper known display techniques are called, with which attempts to imitate ink or ink on paper.
  • E-paper reflects the light like normal paper. Texts or images are permanently displayed on some of these display techniques without the need for a sustain voltage. However, the ad can be changed at a later time.
  • the advantage of using an e-paper as a display of an industrial switchgear is that the device does not need to have its own power supply. The energy required to change the display can be provided with the transmission of the new display value.
  • the adjustment knob 21 is operated by an operator with a slightly higher force than would be necessary if there were no device according to the invention for tracking a trim potentiometer or a switch for setting a switchgear parameter.
  • the rotor plates 22, 70 slide over the piezo elements 50, 60 away.
  • the described two-sided construction of the piezo motor can alternatively also be carried out on one side by omitting the piezo elements 60 or piezo elements 50.
  • the pressure force of the corresponding rotor plate 70 or 22 must be ensured in other ways. This can be done for example by the provision of a spring to the front panel 10 or the circuit board 100 out.
  • the size of the possible power transmission is at least halved. According to the invention, in this case too, the adjusting knob 21 is tracked so that the parameter value which can be read on the display corresponds to the parameter value currently set by the remote setting.
  • a trimming potentiometer instead of a trimming potentiometer, another suitable adjusting element, such as e.g. a tap changer, be provided.
