Description of the invention (The invention is a control device for turning on / off the electrical switching actuator: ~ ^ Equipped with private and / or transmission networks, relays in related methods, insulation status, automatic switching, etc. = Specifically, the invention relates to a control device that makes it possible to adjust the control parameters input to the actuator in real time, so that the required motion rules can be obtained for the moving part of the switching actuator moved by it. Regarding the control 2 sent by the control panel or by the protection logic, the operation of switching actuators can be performed; in particular, sending this signal to the unanimous action can cause the switch & 〈switching actuators to perform corresponding opening or closing operations. The actuators used in the prior art for this purpose are generally mechanical and operate according to non-adjustable motion rules without allowing them to be applied to the switching actuator "Controlled by force. Therefore, the operating condition of the actuator can be defined" "Combined from two parts", in other words, the added force is either maximum or maximum. This generally leads to the actuator and the energy storage system required to feed it. Each of them is extra large in order to accompany every possible use of the switching actuator in its operating life. Brother. According to the situation, the switching actuator mostly supplies more energy than it actually needs to operate, which has an effect on the energy efficiency of the system. Adverse effects and increased wasted energy in shocks at the end of operation. The result is high mechanical stress on the switching actuator and low overall system reliability. In addition, the use of these actuators is not possible once it starts Stop operation, this prevents an actuator from improving the co-location of disconnectors in the electrical network; for example, 'Once the disconnection circuit has begun, it is impossible to cancel its operation.

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs and the connected load service was interrupted for no reason. Do n’t pay attention to it—what ’s wrong: Use this type of actuator with non-adjustable motion rules to obtain the opening or closing operation (at the same time, the phase of all three phases and electrical parameters is generally asynchronous, in other words, the phases are not The blood electrical network has any time relationship; in many cases, this can cause the transient current in the electrical network due to the pre-shock phenomenon during closing and the re-shock phenomenon during opening. In particular, depending on the existing load in the electric network Depending on the type, performing operations at non-optimal moments will produce high-frequency oscillations, which have high amplitude compared to the rated electrical parameters of the electrical network; for example, the current may even cause the rise to be higher than the rated current by several numbers. These transient currents obviously ^ the electrical network is subject to abnormal stress and has a potential that reduces the expected life of the equipment connected to the electrical network; and in any case will cause greater wear and tear of the switching actuator contacts and thus reduce its service life According to the previous technology, some solutions have been proposed for the purpose of synchronizing the operation of the switching actuator with the electrical network, where this network is used to limit the above It should be emphasized that the user can consider that the opening and / or closing operation is synchronous, that is, an ideal tripping time has been set relative to the type of load and the mode of connecting it to the electrical network, such as zero voltage or induction of capacitors. The voltage at the peak of the load is a synchronous time window based on the ideal time. The transient current obtained is sufficiently low. One of the proposed methods is described in US Patent No. 5 119260, which faces problems. It is about the natural path of the relative current passing through zero to open synchronously at a predetermined time and an inductive load so as to avoid overpressure. According to this patent application, there are operating time, measured during one or more previous operations, so that Paper size applies to China National Standard (CNS) A4 (210 X 297 mm) —--------- --------- Order —.— Line (Please read the notes on the back first Fill out this page again}

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, holding the open operation within the synchronized time window. Want to consider the facts: the operating time is not constant but varies with the ambient temperature and the temperature of the open coil. These temperatures are supplied to the controller using a Shida sensor. This controller is equipped with a system that can specifically check the change in operating time with respect to temperature measurement. Also, to consider the possible change in operating time with respect to the time period that has elapsed between two consecutive operations, the controller also receives This time period is measured and used to correct the operating time envisaged using a particular predetermined function. Relative to the situation observed in the previous operation of the towel and the influence factor considered, the control time relative to the assumed zero, i.e. the temperature and the time that has elapsed between two consecutive operations, is then calculated. Therefore, this method assumes that the electrical = mechanical effect of this device relative to the above-mentioned variables is precisely known; this understanding is obtained from the test samples of the device—test stage: execution (specific measurement, about each possible similar switching actuator manufactured) It is very important to consider this sample for the condition of the product. The main limitation of the hanging method lies in who can represent the action of a specific circuit breaker. Accuracy is especially considered during its operating life. f. Furthermore, the use of the processor to calculate the actual operating time spent in real time makes it possible to evaluate the errors committed, relative to the scheduled operating time, only at the end of the operation itself and therefore preventing any corrective action in its execution; @Assess the added corrections relative to the pre-S operation. It is impossible to guarantee that the synchronization situation will not be hindered in the next operation.

Description of the invention (in the US patent Case No. 5,36U84 states that in addition, the method is related to the control of the open circuit or insulation in the two stages of opening and closing. The best time to take the operation is the closed zero voltage and the open zero current. In particular, in In the device described, the actual operating time taken is recorded during each operation. In addition, the device has a device that detects transient currents in order to verify whether the operations have been performed synchronously. If this is not the case, the device can generate corrections and subsequently The scheduled operating time of the operation and one of the signals of synchronous operation are obtained; in addition-the appropriate ambient compensation system makes it possible to perform further corrections which take into account the influence of temperature and the effect of atmospheric pressure on the scheduled operating time. Therefore, the main limitation of the approach is to- Fact: This device relies on prior knowledge of the function of the breakers and / or insulators relative to the factors of the project. In addition, it operates after the results of previous operations Proper corrections between them can cause oscillations and do not ensure synchronization. Finally, taking the zero voltage at turn-off and the 2 current at turn-on as the optimal time to perform the operation may limit the possible application of the device; for example, it is completely unsuitable for Inductive load is closed. According to this method, by selecting, the synchronization mode of the electrical network signal can have a close step error. The network signal is the use of the voltage reference and the current reference measured by a phase angle that is later recognized to be a constant. The determination, or the moment when the zero voltage is passed by a single measurement, is assumed that the electrical network is symmetrical and therefore the operation has a delay of 120 electrical degrees. This method of detecting the reference time (zero) can make the system ineffective due to the voltage loss. That is, in the presence of transient current components, it is more generally 'due to network parameters with harmonic or asymmetric components, so this method is not suitable for synchronous opening of faults.

As shown in FIG. 4, according to a preferred example of the device of the present invention, it is processed And the synchronization device 33 of the controller 100 can provide information for switching the actuator on and off in synchronization with the electrical network. These synchronization devices are used to detect the voltage of the electrical network and the phase of the core, such as a current dust collector And voltage transformer 31, which can receive the information of tracking the electrical parameters of the network 3 2; relative to this information, the synchronization device, through proper calculation, can predict the continuity of zeros and the maximum current and voltage phases after detecting these phases, It also takes into account frequency changes, harmonics, and single-phase transient currents.
