[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0026] See Figure 1-4 This embodiment describes a heating system for a camera condenser body, which includes a heating device 2, a temperature sensor 3, and a control box 5. The control box 5 is equipped with a control system 1 and a DCS communication module 4. The control system 1 is electrically connected to the heating device 2, the temperature sensor 3, and the DCS communication module 4.

[0027] In this embodiment, temperature data and equipment status are transmitted to the monitoring system through DCS communication module 4 to ensure data real-time performance and accuracy.

[0028] The control system 1 includes an automatic mode and a manual mode. In the automatic mode, when the temperature sensor 3 detects that the internal air temperature of the synchronous condenser is lower than the set lower limit, the control system 1 automatically starts the heating device 2. When the temperature sensor 3 detects that the internal air temperature of the synchronous condenser is higher than the set upper limit, the control system 1 automatically stops the heating device 2. In the manual mode, the operator can manually start or stop the heating device 2 through the control box 5.

[0029] This embodiment includes a heating device 2, a temperature sensor 3, and a control box 5. The heating device 2 is controlled by a control system in the control box 5. In automatic control mode, the system can automatically start or stop the heating device 2 based on the real-time monitoring data of the temperature sensor 3, ensuring that the air temperature inside the synchronous condenser is always kept within a reasonable range. This effectively prevents the equipment from being damaged by condensation at low temperatures. This high-precision temperature control not only improves the operational safety of the equipment but also extends its service life.

[0030] The control system 1 described in this embodiment has two control modes: automatic and manual. Operators can switch between them flexibly according to actual needs. The control box 5 is equipped with a rotary switch to adjust the automatic and manual modes, which is simple and convenient to operate. At the same time, the system also has a remote communication function, which can interact with the DCS system to realize remote monitoring and operation, and facilitate equipment management and maintenance.

[0031] The control box 5 is equipped with a rotary switch for adjusting automatic and manual modes. The rotary switch has three positions: "manual", "stop" and "automatic", which are used to switch between automatic and manual modes.

[0032] The heating device 2 includes a fixed connecting plate 6, a terminal box 7, a PTC heater, and a ventilation hood 8. The ventilation hood and the terminal box 7 are respectively disposed on both sides of the fixed connecting plate 6. The PTC heater is disposed inside the ventilation hood 8 and connected to the fixed connecting plate 6. The heating device 2 also includes a fan disposed at one end of the PTC heater. In this embodiment, the heater is a PTC heater, which has self-limiting temperature characteristics and can automatically reduce power after reaching the set temperature to avoid energy waste. The design of the fan and ventilation hood further improves the heating efficiency, ensures rapid and uniform heating of the air inside the machine, and reduces unnecessary energy consumption. In addition, the system has seismic resistance and can meet the environmental requirements of seismic intensity VIII and peak ground acceleration of 0.2g, adapting to harsh environments such as high altitude and high humidity.

[0033] In this embodiment, the terminal box 7 is made of stainless steel 304, with an IP55 protection rating and a wall thickness of not less than 2.5mm, and is used for electrical connections.

[0034] In this embodiment, the heating device 2 adopts a hood design to prevent internal parts of the ventilation hood 8 from falling into the camera converter, thereby further improving the safety of the device operation.

[0035] The fixed connecting plate 6 has multiple screw holes around its perimeter. These screw holes are used for bolt connection between the fixed connecting plate 6 and the camera body in the heating device 2.

[0036] The ventilation hood 8 has multiple ventilation holes 9 at one end. The ventilation holes 9, in conjunction with the fan design, improve the heating efficiency of the heating device 2, ensuring that the air inside the machine is heated quickly and evenly, reducing unnecessary energy consumption. By adjusting the layout of the ventilation holes 9 and the fan speed of the ventilation hood 8, the air circulation efficiency is optimized, so that the temperature uniformity error inside the camera is controlled within ±1℃, and the energy consumption is reduced by about 15%.

[0037] The control system 1 is connected to the heating equipment 2, temperature sensor 3 and DCS communication module 4 via connecting cables. In this embodiment, the connecting cable system uses low-temperature resistant and flame-retardant cables to ensure reliability and safety in high-altitude and low-temperature environments.

[0038] In this embodiment, when the internal air temperature of the camera is lower than the set lower limit or higher than the set upper limit, the control system 1 will issue an alarm via the indicator lights of the control box 5 for low temperature and high temperature, respectively.

[0039] The installation steps in this embodiment are as follows:

[0040] Step 1: Installation of heating device 2: Secure the fixing plate 6 to the preset installation position of the condenser body using stainless steel bolts through the multiple screw holes around its perimeter. Ensure that the contact surface between the fixing plate 6 and the condenser body is flat to prevent loosening due to vibration. Embed the PTC heater into the ventilation hood 8 and securely connect it to the fixing plate 6. The multiple ventilation holes 9 at one end of the ventilation hood 8 face the inside of the condenser to promote air circulation. Install a fan at one end of the PTC heater, ensuring that there is an appropriate gap between it and the inner wall of the ventilation hood 8 to avoid friction during operation. The terminal box 7 is installed on the other side of the fixing plate 6. The internal wiring terminals are made of stainless steel (IP55 protection level) and are used to connect the PTC heater, fan, and control cables.

[0041] Step 2: Installation of temperature sensor 3: Install temperature sensor 3 in the area inside the synchronous condenser near the key components to monitor the air temperature inside the synchronous condenser in real time. Use a high-temperature shielded cable to connect it to the control box 5 to ensure accurate temperature measurement.

[0042] Step 3: Installation of Control Box 5: Control Box 5 is installed on the operating layer of the synchronous condenser, with an IP54 protection rating. The box contains Control System 1, DCS Communication Module 4, and rotary switches. Control Box 5 is connected to Heating Equipment 2, Temperature Sensor 3, and DCS Communication Module 4 via low-temperature resistant and flame-retardant connecting cables. The cable joints are waterproof and sealed to ensure reliability in high-humidity environments.

[0043] During the shutdown of the camera, the control system 1 enters automatic mode by default. The temperature sensor 3 monitors the internal temperature in real time. If the temperature is lower than the set lower limit, the PTC heater starts and works with the fan to accelerate air circulation. After the temperature reaches the upper limit, the heater stops automatically and the fan shuts off after a delay to dissipate heat.

[0044] Under special operating conditions (such as maintenance or debugging), operators can manually start and stop the heating equipment 2 through the control box 5 and view the temperature data in real time to meet special needs.

[0045] The heating system described in this embodiment uses internal circulation during the heating process, without introducing external air sources, thus ensuring a clean and safe internal air environment.

[0046] The embodiments of this utility model disclosed above are merely illustrative of the present utility model. The embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
