Fig. 1 shows a preassembled transformer substation according to the present application.
The transformer substation comprises a transformer substation body, a shell, a box door, a 2-encoder and a 3-control panel, wherein the transformer substation body is 101, the shell is 102, and the box door is 2.
Detailed Description
The technical solutions in the embodiments shown in the present application will be clearly and completely described below with reference to the drawings in the embodiments shown in the present application.
Referring to fig. 1, a preassembled transformer substation includes a transformer substation body 1, where the transformer substation body 1 includes a casing 101 and a box door 102; a voltage sensor, a current sensor and a human body sensor are arranged on the casing 101, a control panel 3 is arranged on the box door 102, and signals detected by the voltage sensor, the current sensor and the human body sensor are transmitted to the control panel 3; the control panel 3 comprises a controller, a display and an alarm; after the controller receives a signal detected by the human body sensor, the voltage sensor and the current sensor are controlled and received for detection; when the detected value of the voltage sensor and/or the current sensor is larger than the preset value, the controller controls the alarm to give an alarm, and the numerical value detected by the voltage sensor and the current sensor is displayed on the display.
Therefore, the prepackage type transformer substation of this application can judge whether have personnel to be close to transformer substation body 1 through human sensor, after personnel are close to the transformer substation predetermined distance, control voltage sensor and current sensor are right the voltage and current of shell detect, and when the testing result was greater than the setting, the alarm will send out the police dispatch newspaper, and suggestion personnel notice safety. Therefore, the prepackage type transformer substation personnel of this application are difficult in danger, and the display of this application still can show alarm information moreover, makes things convenient for personnel to know the condition, convenient and practical, and the security is high.
The human body sensor consists of an infrared imager and an ultrasonic sensor; the infrared imager is used for judging the approaching object as a human body; the ultrasonic sensor is used for judging the distance of the approaching human body. The thermal infrared imager is detection equipment which detects infrared heat in a non-contact manner, converts the infrared heat into a thermal image and a temperature value, displays the thermal image and the temperature value on a display and can calculate the temperature value. The thermal infrared imager can accurately quantify the detected heat and can accurately identify and strictly analyze the heating fault area. After the infrared thermal imager judges that the object is a human body, the ultrasonic sensor transmits ultrasonic waves, then the distance of the human body is judged according to the reflected ultrasonic waves, and after the distance of the human body enters a preset range, the voltage sensor and the current sensor are controlled to detect the voltage and the current of the shell. The preassembled transformer substation can be used for judging the human body and judging the distance, so that an alarm is sent to a person more pertinently, and the safety of the preassembled transformer substation is high.
An encoder 2 is arranged at the joint of the box door 102 and the outer shell 101, and the encoder 2 is used for converting the circular motion of the box door 102 into an electric signal and transmitting the electric signal to the controller; encoder 2 converts the angle displacement into the signal of telecommunication, therefore the prepackage type transformer substation of this application can judge that chamber door 102 is in the closed condition, if chamber door 102 is in the closed condition, works as voltage sensor and current sensor are right the voltage and current of shell detects, and when the testing result was greater than the setting, the alarm sent out the police dispatch newspaper. When the box door 102 is opened and the detected value of the voltage sensor and/or the current sensor is larger than the preset value, the controller controls the breaker in the substation body 1 to be disconnected and displays the disconnected information on the display. Therefore, the applied preassembled transformer substation is high in safety.
When the voltage of the detection value of the voltage sensor and/or the current sensor is larger than 36 volts and/or the current is larger than 16 milliamperes, the alarm continuously flickers and buzzes. The safety voltage of a human body is lower than 36 volts, the current is lower than 16 milliamperes, and therefore, when the safety voltage exceeds the range, people can die, and when the safety voltage is higher than 36 volts and/or the current is higher than 16 milliamperes, people can die easily, so that the alarm continuously flickers and sends out buzzing sounds to remind people of paying attention, safety measures are taken, and then operation is carried out, and the safety of the applied prefabricated substation is improved.
The display is also used for displaying the voltage and current information, the temperature information and the equipment running state information of the pre-installed substation. The preassembled transformer substation can display various information, so that personnel can know the state of the equipment and master safety information conveniently, and the safety is high.
To sum up, the prepackage type transformer substation of this application can send out the police dispatch newspaper, and the suggestion personnel pay attention to safety to can show alarm information, make things convenient for personnel to know the condition, have convenient and practical, the high characteristics of security.
