Description

Technical Field

[0001] This utility model relates to the field of reactors, specifically a reactor with an installed fiber optic sensor. Background Technology

[0002] Reactors, also called inductors, are widely used in circuits. Due to the effect of electromagnetic induction, they possess inductance, which helps to impede changes in current. Common reactors used in power systems are series reactors and shunt reactors. Reactors are connected in either series or parallel configurations. Series reactors typically function as current limiters, while shunt reactors are frequently used for reactive power compensation.

[0003] Reactors generate heat during operation. If their temperature is not monitored and controlled in time, the reactor may overheat, leading to aging or burning of the insulation material. Furthermore, the performance of the reactor is affected by temperature. To monitor the reactor temperature in real time and accurately, we propose a reactor equipped with an optical fiber sensor. Utility Model Content

[0004] The purpose of this invention is to provide a reactor for mounting fiber optic sensors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a reactor for mounting fiber optic sensors includes a reactor body:

[0006] One end of the temperature-sensing optical fiber is provided with a temperature-sensitive fluorescent material and installed in the air duct of the reactor body to monitor the internal temperature of the reactor and convert the monitored temperature into an optical signal output.

[0007] The temperature transmitter is used to demodulate the optical signal output from the temperature sensing fiber, and the resulting temperature data is output to the host computer.

[0008] Furthermore: the temperature-sensing optical fiber includes an optical fiber output interface and a temperature-sensing probe. The optical fiber output interface is fixedly installed at the input end of the temperature transmitter, and the temperature-sensing probe is fixedly installed inside the air duct of the reactor body.

[0009] Furthermore: the reactor body includes clamps, busbars, iron core, coils and base, and two clamps are fixedly installed at both ends of the reactor body by fixing bolts.

[0010] Furthermore, a tag is provided on the outer side of the temperature-sensing optical fiber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the problem of temperature transmission lag is improved by using temperature-sensing optical fibers and temperature probes. The temperature signal is converted into an optical signal for transmission through fluorescent optical fiber temperature measurement. Because optical signal transmission is used, it is not easily affected by electromagnetic interference and is suitable for temperature monitoring in strong electromagnetic environments of reactors. It can also realize real-time monitoring of the internal temperature of the reactor, thereby helping to avoid overheating of the reactor, extending the service life of the equipment, preventing overheating of the reactor, helping to optimize the working conditions of the reactor, thereby reducing faults, extending equipment life, and improving the efficiency of the entire power system.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 The figure shows a preferred embodiment of this utility model, a reactor for mounting an optical fiber sensor, comprising a reactor body:

[0018] One end of the temperature-sensing optical fiber 2 is provided with a temperature-sensitive fluorescent material and installed in the gas channel of the reactor body to monitor the internal temperature of the reactor and convert the monitored temperature into an optical signal output.

[0019] Temperature transmitter 10 is used to demodulate the optical signal output by temperature sensing fiber 2, and the resulting temperature data is output to the host computer.

[0020] It is understood that the temperature sensing fiber 2 includes a fiber optic output interface 1 and a temperature sensing probe 3. The fiber optic output interface 1 is fixedly installed at the input end of the temperature transmitter 10, and the temperature sensing probe 3 is fixedly installed in the air duct of the reactor body. The temperature sensing probe 3 has a special fluorescent material that emits light signals of different intensities due to temperature changes. Temperature data is transmitted using this light signal. The fiber optic output interface 1 is connected to the temperature transmitter 10.

[0021] Specifically: The reactor body includes clamps 4, wire bars 5, iron core 6, coils 7 and base 9. Two clamps 4 are fixedly installed at both ends of the reactor body by fixing bolts 8.

[0022] When the reactor is in operation, after the power supply is connected to the reactor, the current begins to flow through the coil 7. The current in the coil 7 generates a changing magnetic field. As the current increases, the magnetic field around the coil 7 gradually strengthens. The iron core 6 can concentrate and strengthen this magnetic field, increasing the inductance value. Due to the inductive characteristics of the reactor, the change in current is limited. The reactor will react to the current, thereby affecting the amplitude and phase of the current. This reactive effect helps to suppress instantaneous changes in current and protect other equipment in the circuit. In the coil 7, the changing current causes energy to be stored in the inductance and released when the current decreases or changes. During normal operation, the reactor will continuously regulate the current to ensure that the voltage and power factor of the system are kept within the set range. It can also reduce the impact of harmonics and improve the overall performance of the system.

[0023] It should be added that a label is set on the outside of the temperature sensing fiber 2; the label indicates the channel number, and it must be connected to the channel with the corresponding number of the temperature transmitter 10.

[0024] In this embodiment, the temperature transmitter 10 can demodulate the input optical signal, and the resulting temperature data is output through the RS485 communication interface. It supports the standard Modbus RTU protocol and is connected to a 220V power supply and A+ and B- signal lines.

[0025] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
