The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0030] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, not necessarily to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units need not be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0031] Figure 1 is a schematic diagram of a capacitive voltage transformer provided according to the embodiments of the present application, as shown in Figure 1 The capacitive voltage transformer includes a frequency relay arranged in a secondary winding of an intermediate transformer, for detecting a voltage frequency in a circuit in which the capacitive voltage transformer is located, wherein the intermediate transformer is an intermediate transformer in an electromagnetic unit of the capacitive voltage transformer; a connection plate connected with the intermediate transformer, for adjusting a working frequency of the capacitive voltage transformer according to the voltage frequency; and a compensation reactor connected with the connection plate, for adjusting a reactance value in the circuit according to a terminal of the connection plate.

[0032] For example, the capacitive voltage transformer is composed of a voltage divider capacitor and an electromagnetic unit, wherein the main devices in the electromagnetic unit include an intermediate transformer, a compensation reactor, a voltage limiting device, a damper, etc. In addition, Figure 2 is a wiring schematic diagram of a capacitive voltage transformer according to the prior art, as shown in Figure 2As shown, U1 represents the rated voltage of the line, C1 represents the high-voltage capacitor in the voltage divider capacitor, C2 represents the medium-voltage capacitor in the voltage divider capacitor, UT represents the voltage across the medium-voltage capacitor C2, L represents the compensating reactor, T represents the intermediate transformer, and Z2 represents the secondary load. Furthermore, the voltage divider capacitor can be considered a two-port network, with the input being the high-voltage terminal and ground, and the output being the medium-voltage terminal and ground. The electromagnetic unit can be considered an electromagnetic voltage transformer.

[0033] Furthermore, according to the principle of equivalent generators in electrical engineering, a capacitive voltage transformer can be equivalently transformed into something like... Figure 3 The circuit diagram shown is as follows. Where Xc and Rc are the equivalent capacitive reactance and resistance; XL and RL are the inductive reactance and resistance of the reactor; X0 and R0 are the excitation inductive reactance and resistance of the intermediate transformer; X1, R1, X2', and R2' are the winding leakage reactance and resistance; ZB' is the load impedance; Uc is the intermediate voltage; U2' is the secondary voltage; I1 is the primary current; I0 ​​is the excitation current; and I2' is the secondary current. Therefore, from... Figure 2 It can be seen that, in order to keep the secondary phase angle the same as the primary phase angle, the leakage reactance of the intermediate transformer X0 and the compensating reactor XL should be canceled out by the capacitive reactance Xc of the voltage divider capacitor. Furthermore, the inductive reactance of the compensating reactor is 2*pi (pi)*fr (frequency)*L (inductance), so when the frequency changes, XL will also change, causing a change in the secondary phase angle.

[0034] For example, Figure 4 The wiring diagram of the capacitive voltage transformer provided in the embodiments of this application is as follows: Figure 4As shown, Upr represents the line rated voltage, C1 represents the high voltage capacitor, C2 represents the medium voltage capacitor, N represents the low voltage terminal of the voltage dividing capacitor, X represents the tail end of the electromagnetic unit, G represents the ground terminal, L represents the compensation reactor, A plate and B plate respectively represent the connection plate in the connection plate, K1, K2, K3, K4, K5, K6, K7, K8 respectively represent the terminals in the A plate and B plate, F represents the lightning arrester, AT represents the high voltage terminal of the intermediate transformer, R represents the parallel resistance, Ld represents the damping reactor, Rd represents the series resistance, wherein R, Rd and Ld can be combined into one device, that is, the damper (which can be represented by D), 1a and 1n represent the main 1 winding, da and dn represent the residual voltage winding, d1 and d2 represent the connection terminals of the damping device, and KF represents the frequency relay. Moreover, the frequency relay KF is installed in the secondary winding of the capacitive voltage transformer to measure the voltage frequency of the actual circuit; the connection plate (A plate and B plate) and the intermediate transformer in the capacitive voltage transformer are connected, which can also be called a mechanical device that acts according to the frequency, which is used to act according to the frequency after the frequency relay KF collects the frequency, so as to adjust the working frequency of the capacitive voltage transformer; the compensation reactor and the terminal of the connection plate (A plate and B plate) are connected, which can also be called a device for adjusting the reactance, which is used to adjust the reactance according to the terminals (K1-K8) of the connection plate (A plate and B plate). In addition, the connection plate is installed in the electromagnetic unit of the capacitive voltage transformer, and the intermediate transformer and the compensation reactor are the main components in the electromagnetic unit of the capacitive voltage transformer.

[0035] In summary, the capacitive voltage transformer provided by the embodiment of the present application detects the voltage frequency in the circuit in which the capacitive voltage transformer is located through the frequency relay 10 arranged in the secondary winding of the intermediate transformer, wherein the intermediate transformer is the intermediate transformer in the electromagnetic unit of the capacitive voltage transformer; the connection plate 20 connected with the intermediate transformer adjusts the working frequency of the capacitive voltage transformer according to the voltage frequency; and the compensation reactor 30 connected with the connection plate 20 adjusts the reactance value in the circuit according to the terminals of the connection plate 20, thereby solving the problem that the capacitive voltage transformer in the related art can only work at one frequency, which leads to a small use range of the capacitive voltage transformer. By adjusting the reactance value in the circuit in which the capacitive voltage transformer is located through the compensation reactor according to the terminals of the connection plate, and adjusting the working frequency of the capacitive voltage transformer through the connection plate according to the voltage frequency in the circuit detected by the frequency relay, the capacitive voltage transformer can work at multiple frequencies, thereby achieving the effect of expanding the use range of the capacitive voltage transformer.

[0036] Optionally, in the capacitor voltage transformer provided by the embodiment of the present application, the connecting plate comprises: a base arranged in the electromagnetic unit of the capacitor voltage transformer; an adjusting plate arranged in the base; a spring for connecting the first end of the base and the adjusting plate; a moving plate connected with the second end of the adjusting plate; and a direct-current electromagnet arranged at the corresponding position of the base and the moving plate.

[0037] For example, Figure 5 is a schematic diagram of the connecting plate of the capacitor voltage transformer in the embodiment of the present application, as Figure 5 shown, the connecting plate is composed of the base, the adjusting plate, the spring, the moving plate and the direct-current electromagnet. The base is installed in the electromagnetic unit, and the base has a guide groove and a terminal. The moving plate can be clamped into the guide groove, and the moving plate is made of soft magnetic material and can be clamped into the base at both ends. In addition, the spring can be used to connect one end of the base and the adjusting plate, and the nylon belt can be used to connect the other end of the moving plate and the adjusting plate. Moreover, the direct-current electromagnet is installed at the corresponding position of the base and the moving plate, and the direct-current electromagnet can be controlled by the contact of the frequency relay KF.

[0038] Through the structure of the connecting plate described above, the smooth movement can be ensured, the installation of the contact is facilitated, and the contact can be freely combined to realize different wiring.

[0039] Optionally, in the capacitor voltage transformer provided by the embodiment of the present application, the winding of the compensation reactor is connected with the terminal of the adjusting plate.

[0040] For example, all the windings of the compensation reactor are arranged in the relationship of 2-5 times of the number of turns in an increasing manner (for example, the first group is 10 turns, the second group can be 50 turns, the third group is 250 turns, and so on). That is, the windings of the compensation reactor are respectively connected to the terminals (K1-K8) of the fixed seat (the connecting plate (A plate and B plate) described above) according to certain rules, that is, K1-K2 (50 turns), K3-K4 (250 turns) and so on.

[0041] Through the above scheme, all the windings of the compensation reactor can be freely combined according to the calculation and the test, so that the reactance can be adjusted.

[0042] Optionally, in the capacitor voltage transformer provided by the embodiment of the present application, the adjusting plate comprises a first connecting plate, and when the frequency relay is in a non-working state, the terminal of the first connecting plate is connected with the terminal of the base through the spring.

[0043] For example, the A board can be a 50Hz connection board, and the B board can be a 60Hz connection board. Then according to the test or calculation result, the connection order of the 50Hz corresponding compensation reactor is connected to the 50Hz connection board, and the connection order of the 60Hz corresponding compensation reactor is connected to the 60Hz connection board. When the frequency is 50Hz, the initial contact of the 50Hz connection board is connected with the outgoing terminal of the compensation reactor, and the 50Hz connection board is connected with the fixed plate terminal under the action of the spring tension, so that the product can be normally used under 50Hz.

[0044] The capacitor voltage transformer can be used under one of the working frequencies through the action of the spring tension in the connecting plate.

[0045] Optionally, in the capacitor voltage transformer provided in the embodiments of the present application, the adjusting plate comprises a second connection board, when the frequency relay is in the working state, the DC electromagnet moves the moving plate, the moving plate moves the adjusting plate, and the terminal of the second connection board is connected with the terminal of the base.

[0046] For example, after the connection order of the 50Hz corresponding compensation reactor is connected to the 50Hz connection board and the connection order of the 60Hz corresponding compensation reactor is connected to the 60Hz connection board according to the test or calculation result, when the frequency is 60Hz, the frequency relay contact is actuated, and the DC electromagnet is connected. The electromagnet attracts the moving plate, thereby pulling the adjusting plate, and the 60Hz connection board trigger head is connected to the compensation reactor terminal, and the terminal of the 60Hz connection board is connected with the terminal of the base, so that the product can work under 60Hz.

[0047] Through the control of the action of the DC electromagnet, the movement of the mechanical mechanism can be driven, so that the capacitor voltage transformer can be used under another working frequency. That is, the capacitor voltage transformer can meet the use requirement of more frequencies.

[0048] Figure 6 The flow chart of the processing method of the capacitor voltage transformer provided in the embodiments of the present application is shown in FIG. 6, which comprises the following steps: Figure 6

[0049] In step S601, the voltage frequency in the circuit where the capacitor voltage transformer is located is acquired.

[0050] For example, the detection device for detecting the frequency is arranged in the secondary winding of the capacitor voltage transformer, that is, the frequency relay KF can be installed in the secondary winding of the capacitor voltage transformer, and the voltage frequency of the actual circuit is measured through the frequency relay KF.

[0051] In step S602, the working state of the frequency relay in the capacitor voltage transformer is determined according to the voltage frequency in the circuit.

[0052] ​For example, after the detection device detects the voltage frequency of the actual circuit, it is determined whether the frequency relay is in the working state or in the non-working state according to the detected voltage frequency of the actual circuit.

[0053] In step S603, the working frequency of the capacitive voltage transformer is determined according to the working state of the frequency relay.

[0054] For example, when the frequency relay is in the non-working state, the capacitive voltage transformer can be used at a frequency of 50 Hz; when the frequency relay is in the working state, the capacitive voltage transformer can be used at a frequency of 60 Hz.

[0055] Through the above steps S601 to S603, the working state of the frequency relay in the capacitive voltage transformer is determined according to the voltage frequency in the circuit where the capacitive voltage transformer is located, and the working frequency of the capacitive voltage transformer is determined according to the working state of the frequency relay, so that the capacitive voltage transformer can work at multiple frequencies, thereby achieving the effect of expanding the use range of the capacitive voltage transformer.

[0056] In order to enable the capacitive voltage transformer to meet the use requirements of more frequencies, in the processing method of the capacitive voltage transformer provided in the embodiment of the present application, the capacitive voltage transformer can also meet the use requirements of more frequencies through the following steps: the capacitive voltage transformer at least includes a connecting plate, and the connecting plate at least includes a base, an adjusting plate, a spring, a moving plate and a direct current electromagnet; if the frequency relay is in the non-working state, the terminal of a first wiring plate in the adjusting plate is connected with the terminal of the base through the spring, wherein the frequency corresponding to the first wiring plate is the first working frequency of the capacitive voltage transformer; if the frequency relay is in the working state, the moving plate is moved through the direct current electromagnet, the adjusting plate is moved through the moving plate, and the terminal of a second wiring plate in the adjusting plate is connected with the terminal of the base, wherein the frequency corresponding to the second wiring plate is the second working frequency of the capacitive voltage transformer.

[0057] For example, the A board can be a 50Hz terminal board, and the B board can be a 60Hz terminal board. Then according to the test or calculation result, the terminal connection order of the compensation reactor corresponding to 50Hz is connected to the 50Hz terminal board, and the terminal connection order corresponding to 60Hz is connected to the 60Hz terminal board. When the frequency relay is in the non-working state, the contacts of the 50Hz connection board are initially connected to the outgoing terminals of the compensation reactor, and the 50Hz terminal board is connected to the terminal of the fixed plate under the action of the spring tension, so that the capacitor voltage transformer can be normally used at 50Hz; when the frequency relay is in the working state, the frequency relay contacts act, the DC electromagnet is turned on, the electromagnet attracts the moving plate, the adjusting plate is pulled, and the 60Hz terminal board trigger head is connected to the terminal of the compensation reactor, and the terminal of the 60Hz terminal board is connected to the terminal of the base, so that the capacitor voltage transformer can work at 60Hz.

[0058] Through the above scheme, the capacitor voltage transformer can be used at 50Hz and 60Hz frequencies, so that the capacitor voltage transformer can meet the use requirements of more frequencies.

[0059] In order to make the first terminal board generate a first working frequency and the second terminal board generate a second working frequency, in the processing method of the capacitor voltage transformer provided in the embodiment of the application, the first terminal board can generate the first working frequency and the second terminal board can generate the second working frequency by the following steps: the capacitor voltage transformer further comprises a compensation reactor, a plurality of windings of the compensation reactor are determined according to a preset rule, and a plurality of compensation reactors are obtained; and each compensation reactor is connected to the terminal board corresponding to each compensation reactor, so that the first terminal board generates the first working frequency and the second terminal board generates the second working frequency.

[0060] For example, all the windings of the compensation reactor are arranged in a 2-5 times turn number increasing relationship (for example, the first group is 10 turns, the second group can be 50 turns, the third group is 250 turns, and so on), and a plurality of adjusting windings are arranged, that is, the windings of the compensation reactor are connected to the terminals (K1-K8) of the fixed base (the connection boards (A board and B board) described above) according to a certain rule, that is, K1-K2 (50 turns), K3-K4 (250 turns) and so on. Then according to the test or calculation result, the terminal connection order of the compensation reactor corresponding to 50Hz is connected to the 50Hz terminal board, and the terminal connection order corresponding to 60Hz is connected to the 60Hz terminal board.

[0061] Through the above scheme, all the windings of the compensation reactor can be freely combined according to the calculation and the test, so that the reactance can be adjusted, and the frequency can be generated on the corresponding terminal board by connecting the terminal connection order of the compensation reactor to the corresponding terminal board.

[0062] In summary, the processing method of the capacitor voltage transformer provided in the embodiments of the present application acquires the voltage frequency in the circuit in which the capacitor voltage transformer is located; determines the working state of the frequency relay in the capacitor voltage transformer according to the voltage frequency in the circuit; and determines the working frequency of the capacitor voltage transformer according to the working state of the frequency relay, thereby solving the problem that the capacitor voltage transformer in the related art can only work at one frequency, resulting in a small use range of the capacitor voltage transformer. By acquiring the voltage frequency in the circuit in which the capacitor voltage transformer is located, determining the working state of the frequency relay in the capacitor voltage transformer according to the voltage frequency, and determining the working frequency of the capacitor voltage transformer according to the working state of the frequency relay, the capacitor voltage transformer can work at multiple frequencies, thereby achieving the effect of expanding the use range of the capacitor voltage transformer.
