Safety device.
Background technology
Power system security production is the vertical root of body of electric power enterprise.It is prevented during operation construction of transformer substation mechanical work
Accidentally touch the difficult point and blank spot that high-rise electrical body is transformer substation security management work.Traditional screening（It encloses）Column can only solve construction machine
Security protection on tool or the horizontal plane all around of personnel, and the high-rise how anti-construction machinery of electrical body connects above its setting
Near is the difficult point of protected working.Therefore it needs to develop three-dimensional protective device to solve the weak spot in production safety management.
It is effective that the security protection of high-rise electrical body there is no from the point of view of situation about understanding both at home and abroad at present, in substation's operation
Solution.Therefore, the exploitation anti-approach warning system of substation's high level electrical body is to solve the effective ways of problems,
It is also a development with scientific and technical innovation and challenge simultaneously.The application of project is to the safety in production water of raising electric power enterprise
It is flat to have very important meaning.
Overhaul of the equipments scene includes maintenance isolation screening in typical substation（It encloses）Column, repair apparatus, personnel, crane etc.,
At repair apparatus scene, by repair apparatus safe shading（It encloses）Column only sets one being surrounded by repair apparatus in site of road
Entrance is passed in and out, is entered on charging equipment neighbouring outside service area with controllers or other check man's equipments.It is set by maintenance
The standby equipment to have had a power failure, therefore, as long as personnel do not run out of the safe shading（It encloses）Column, it is exactly to pacify that the service work carried out is opposite
Complete.But often also have charged generatrix running by the top of repair apparatus sometimes, overhauling the band under normal circumstances
During goddess of lightning's line bottom device, it is necessary to special safeguard procedures.In the prior art, general way pulls a few road limit for height ropes, but
Since only several straight lines, limit for height effect unobvious are not easy to judge, there are some potential safety problemss when closing on height limit line.
Chinese patent Authorization Notice No. CN203012920U discloses a kind of infrared limit for height instrument of substation, the infrared limit for height
Instrument is arranged at substation gate, including infrared optical emitters, infrared ray light-receiving device, alarm generator and host, wherein：It is infrared
Line photophore is arranged on the side at gate, level sends out infrared beam, and the height of light beam is vehicle and object into substation
The restriction height of body；Infrared ray light-receiving device is arranged on the opposite side at gate, receives infrared beam, infrared ray light-receiving device receiving terminal
Highly it is equal to the height of light beam, the signal input part and alarm generator of the signal output end connection host of infrared ray light-receiving device
Perform signal input part；The manual switch of alarm generator is provided on host, signal output end connection alarm generator

Height when entering plant area can be limited, in practical work process, device height often changes, for example crane exists
It is huge with height difference during lifting operation when driving, therefore the device can not protect the safety of running equipment.
Chinese patent notification number CN202415005U discloses a kind of substation crane sling height attention device, conducive to limit
Height rope one end is arranged on crane, and with alarm triggering device on the ground is set to connect, alarm triggering device includes the other end
The free chamber of traverse and the electrode cavity stood up, free chamber are connected with electrode cavity by interface, setting steel ball, electrode in free chamber
Intracavitary sets electrode, and electrode forms supervisor's attention device alarm electricity with power supply, warning device, alarm lamp and wireless signal transmitter
Road, crane operation person's attention device are made of wireless signal receiver, alarming horn and supply unit.During more than limit for height, limit for height rope
Alarm triggering device is turned in drawing, and steel ball is dropped into electrode cavity, and supervisor's attention device warning circuit is connected, and warning device sends out police
Report, alarm lamp flicker, while the signal of wireless signal transmitter transmitting is received by wireless signal receiver, alarming horn sends out police
Report, so as to and alarm, be automatically reminded to, prevent crane superelevation, avoid accident.The device at runtime, due to crane
Peak is often positioned in the surface of lifting object, and arm of crane needs not stop to move, thus limit for height rope can not ensure on ground
Alarm triggering device connection, therefore be unsuitable for onsite application.
