Wireless digital electric field strength monitoring sensor

Abstract

The invention relates to a wireless digital electric field strength monitoring sensor which consists of a shell body, a power supply circuit, an electric field effect element, an amplifier circuit, an impedance conversion circuit, a quantity value judgment circuit, a power supply control circuit, a PCB (Printed Circuit Board), a singlechip computer circuit, a wireless communication module circuit and an antenna, wherein the power supply circuit, the electric field effect element, the amplifier circuit, the impedance conversion circuit, the quantity value judgment circuit, the power supply control circuit, the PCB, the singlechip computer circuit and the wireless communication module circuit are mounted in the shell body, and the antenna is mounted outside the shell body. The wireless digital electric field strength monitoring sensor has the advantages that the monitoring sensor can detect whether high-voltage equipment is charged or not, can detect the voltage level of a charged body, and can realize lightning and surge discrimination.. The monitoring sensor is small in volume and can be mounted on equipment to be detected without influencing the service function of the equipment to be detected; and the monitoring sensor has another advantage of simple structure, and the number of elements in use is less, so that the manufacturing cost of the sensor is reduced.

Description

technical field [0001] The invention relates to an electric field intensity monitoring sensor for a high-voltage electrified body, in particular to a wireless digital electric field intensity monitoring sensor. The device can also be used to detect whether electric equipment is electrified and the voltage level, and to detect strong electric intrusion such as lightning strikes. Background technique [0002] At present, in order to confirm the protection level of the work area and the voltage protection level of the maintenance operation equipment during the maintenance work of electric equipment, the working voltage level and live state of the equipment under maintenance must be confirmed, so as to ensure the safety of the maintenance operation. The original manual detection method using a high-voltage tester has been eliminated and replaced by an electronic automatic detection method. In the Chinese patent application (Application No. 200610123199.2), a technology using wir...

Problems solved by technology

In the Chinese patent application (Application No. 200610123199.2), a wireless high-voltage live detection display and locking technology is proposed. However, in this technical solution, only a method for detecting whether the high-voltage equipment is charged is proposed, and the high-voltage detection cannot be detected. Equipment live voltage level and strong current intrusion detection such as lightning

Another disadvantage of this technical solution is that the device is large in size and cannot be installed on the equipment to be inspected, so it is necessary to set up a detection platform for it, which increases the cost and difficulty of installation and use.
