Description

Substation concealed area early warning system

technical field

The utility model relates to the field of electric power monitoring, in particular, it is provided with an early warning system for concealed distinctions in substations.

Background technique

At present, with the development of science and technology, technologies such as video analysis, artificial intelligence, and network communication are advancing by leaps and bounds, and play an irreplaceable role in all aspects of people's production and life. The outstanding application of "interconnection", "practicality" and "intelligence" is the focus of power companies.

The power company is responsible for the production management and power marketing work such as the power development planning of the entire management area, the safe and economic operation of the power grid, and the construction and maintenance of power facilities. In order to further improve the management level of substations, ensure the high reliability of power supply, standardize the daily management and equipment operation and maintenance of substations, develop a set of highly integrated, convenient for concealed area layout, sensitive detection and less false alarms as soon as possible. The foreign object intrusion prevention system has become an indispensable part of the power protection link.

At present, the cable trench, cable interlayer, the back of the large monitoring screen, the back of the analog screen, the anti-static floor, and the inside of the screen cabinet are usually used as the main convergence channel and narrow space for cable and circuit transmission in the substation. These areas are difficult to inspect and detect, but they often encounter small foreign objects such as snakes and rats climbing and invading, which often bring uncontrollable safety hazards or equipment damage (such as phase-to-phase short circuit, single-phase grounding, insulation layer damage, power supply breakdown) wait). It is not easy to prevent the consequences of such heavy losses caused by intrusion of foreign objects due to its concealment before the incident. Operation and maintenance inspection personnel often complain about this, saying that the current prevention methods are single and passive, which consume a lot of manpower but are ineffective. And it is hard to guard against.

Utility model content

The technical problem to be solved by the utility model is to realize a system capable of real-time monitoring of hidden areas in substations.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an early warning system for substation hidden areas, the early warning system includes a monitoring unit installed in the hidden area and a monitoring unit in the monitoring room, the monitoring unit and the monitoring unit communicate through the network, the The monitoring unit includes a video camera, a loudspeaker and a supplementary light, and the monitoring unit includes a display and a signal input device.

The monitoring unit is provided with a wireless transmitting device, and the signal collected by the monitoring unit is transmitted to the mobile terminal through the wireless transmitting device.

The supervisory unit is also provided with an infrared trigger sensor and an audio sensor.

The hidden areas include power tunnels, cable trenches, cable interlayers, the back of the large monitoring screen, the back of the simulation screen, under the anti-static floor, and inside the screen cabinet.

A patrol track is set in the power tunnel and/or cable trench, and a movement mechanism is set on the patrol track, and a monitoring unit is fixed on the movement mechanism.

The signal input device includes a microphone and control buttons.

The supervisory unit is provided with a storage unit.

The utility model has the advantage that it is convenient for the staff to monitor the hidden area in real time, greatly reduces the labor intensity and operation difficulty of the personnel patrolling in the hidden area, and solves the hidden danger of inspection blind spots in the traditional original inspection methods of prying cover boards and drilling cable trenches. The staff on duty gets rid of frequent and repetitive inspection work, saves manpower, and allows the on-duty staff to devote more energy to safety management tasks that require people to perform. By issuing detection alarms for foreign object intrusion in hidden areas, it prompts relevant personnel to conduct targeted inspections ,Improve work efficiency. Through the implementation of this system, it is possible to improve the standard operation specification for small animal inspection, reduce the chance of small animals entering switch cabinets, protection cabinets and other screen cabinets, timely and targeted inspection and blockage, and reduce small animals chewing on wires and climbing around. Damage to equipment caused by other reasons, and reduce tripping accidents caused by small animals. Moreover, it can also reduce the on-site input of poisonous baits such as rat poison, and protect the environment.

Description of drawings
