[0019] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0020] Embodiment:

[0021] like Figure 1-5 As shown, the utility model provides a circuit control system for a CT cabin, including an input power supply and a distribution box 2, and electronic components for protecting, displaying and controlling the circuit of the equipment, including a circuit breaker, a lightning arrester, an over-voltage and under-voltage protector, a contactor, a relay, a voltmeter, an ammeter, and a CT start and stop indicator light, wherein the lightning arrester, the over-voltage and under-voltage protector, the circuit breaker, and the contactor are all located in the distribution box 2, and the distribution box 2 is connected to the CT equipment;

[0022] The input power of the CT cabin is an AC380V input power, and a power input port 1 is provided on the cabin. The input power enters the cabin through the power input port 1. The power input port 1 is connected to the distribution box 2. A travel switch 7 is installed at the door frame of the CT cabin. The control circuit of the contactor includes an emergency stop button 4, a start button 5 and a stop button 6. The emergency stop button 4, the start button 5 and the stop button 6 are all arranged inside the operating room of the CT cabin. A warning light 3 is installed above the external door frame of the operating room of the CT cabin. A control box is installed in the operating room. The emergency stop button 4, the start button 5 and the stop button 6 are all installed in the control box. An indicator light for displaying the start and stop status of the CT equipment is arranged on the distribution box 2;

[0023] Working principle: The electrical control system of the CT cabin in this embodiment mainly includes power input, circuit protection, door status detection, warning status triggering, and CT equipment working status control;

[0024] Power input: The CT power supply box of the CT cabin is powered separately from other equipment, and the input power is AC380V. A power input port 1 is provided on the cabin, and the power enters the cabin through the power input port 1;

[0025] Circuit protection: Circuit breakers, lightning arresters, over- and under-voltage protectors, contactors, relays, voltmeters, ammeters, CT start and stop indicator lights are installed in the distribution box 2 in the shelter to protect, display and control the equipment circuit. The total power supply of the CT equipment is controlled by a 125A circuit breaker, which has short-circuit and overload protection. The lightning arrester provides lightning protection for the circuit. The ammeter and voltage transformer display the circuit current and voltage changes in real time. When the voltage increases or decreases abnormally, the over- and under-voltage protection device will automatically cut off the circuit to avoid overload and damage to the electrical equipment.

[0026] Door status detection: In this embodiment, a travel switch 7 is installed at the door frame. The circuit can detect the open, closed or improperly closed state of the operating room door in real time, and convert the position change of the door into an electrical signal for analysis and judgment by the circuit logic;

[0027] Warning status trigger: When the main power switch of the CT equipment is turned on and the operating room door is closed, the warning light 3 outside the door lights up and displays "Working, harmful radiation, do not enter when the light is on", reminding people outside the door not to enter;

[0028] CT equipment working status control: CT power supply is controlled by contactor. The control circuit of the contactor includes three buttons: emergency stop button 4, start button 5 and stop button 6 set in the operation room. The operator can press the corresponding button according to the needs.

[0029] The circuit breaker, lightning arrester, overvoltage and undervoltage protector installed in the circuit can detect the circuit status. When abnormal conditions such as overload, short circuit, overvoltage and undervoltage occur, the circuit can be cut off to ensure the safety of electricity use. It is required to arrange a signal receiving point on the CT equipment, and the door switch of the operation room is connected to the circuit of the CT equipment. The CT equipment can only operate normally when the door of the operation room is detected to be closed.

[0030] In emergency situations, such as equipment failure or personal injury, the CT equipment can be stopped by pressing the emergency stop button 4 outside the operating room door so that personnel can carry out emergency treatment;

[0031] A control box is installed in the operation room, on which the emergency stop button 4, start button 5 and stop button 6 of the CT equipment are arranged. The operator can operate the equipment according to the needs. The indicator light is arranged on the distribution box 2 to display the start and stop status of the CT equipment, which is convenient for personnel to monitor;

[0032] The above operations improve the safety of equipment use, and can effectively protect the CT equipment circuit from lightning, short circuit, overload, undervoltage and overvoltage. This is especially important for high-power electrical CT equipment. The control logic of its electrical system further ensures the safety of users and improves work efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
