A remote control live display locking device

Abstract

The invention relates to a remote-control electrification display locking device which comprises a three-circuit electric field sensor, an isolation amplifying circuit, a data processor, a wireless remote-control module, a temperature and humidity sensor and a display device. The electric field sensor and the temperature and humidity sensor are connected with the data processor through the isolation amplifying circuit. The wireless remote-control module comprises a wireless remote-control emission module and a wireless remote-control receiving module. The wireless remote-control receiving module is connected with the data processor. The safety production of an electric system becomes increasingly important along with the development of the national economy, and therefore the higher requirement for safe, reliable and stable high-voltage locking equipment is raised. By the adoption of the device, the safety, the accuracy and the reliability of installation, debugging and maintenance operation of high-voltage electrification locking are greatly improved, the safety risk is lowered, and the work intensity of operating maintenance personnel is reduced. The safe and stable operation of a power grid is effectively guaranteed, and the powerful support is provided for rapid development of economic construction and building of a harmonious society.

Description

technical field [0001] The invention relates to a device for preventing electrical misoperation, and more specifically, relates to a remote-controlled electrified display locking device. Background technique [0002] Inductive high-voltage live display locking device is a device to prevent electrical misoperation. It is a non-contact high-voltage live detection device. It cooperates with electromagnetic locks and microcomputer anti-misoperation locking devices. Safety interlocks are realized for switch blades and other places that need to be locked to prevent electrical misoperation. [0003] The signal is obtained through the induction of the sensor to the surrounding electric field. This method has defects and deficiencies, mainly in: [0004] (1) The induction value is different when the installation distance is inconsistent or the electric field strength nearby is inconsistent; [0005] (2) The signal is sensed through the air, so changes in the medium parameters in th...

Problems solved by technology

[0004] (1) The induction value is different when the installation distance is inconsistent or the electric field strength nearby is inconsistent;

[0005] (2) The signal is sensed through the air, so changes in the medium parameters in the air (such as temperature, humidity, dust, rain, etc.) will also cause changes in the strength of the sensed signal;

[0006] (3) After long-term use, the dust and dirt accumulated on the sensor head will have a serious impact on the sensing value

[0007] These defects often lead to false alarms of inductive live locking devices

Currently, the only way to deal with changing conditions over time is through constant, manual re-adjustment of baseline values, which significantly increases equipment maintenance costs
