Abstract
The utility model relates to an alarm with an electrically controlled lock for preventing mistakenly entering a charged chamber, which belongs to the field of power generation and transformation of an electric power system, and particularly relates to a device playing active reminding and alarming roles so as to prevent workers from mistakenly entering the charged chamber and mistakenly touching operating equipment as well as to prevent over-range working. Under normal running, the electrically controlled lock of the device is unlocked and sent to a running position; during overhauling, the electrically controlled lock of the device is unlocked and sent to an overhaul position, and a key of the electrically controlled lock is kept by a work approver; and when a maintainer opens a non-overhaul secondary protection screen, a control cabinet and a door of a high-voltage cabinet, a magnetic relay acts and is communicated with a sound alarm chip and a loudspeaker through the electrically controlled lock so as to send alarm sound to remind the worker that the non-overhaul secondary protection screen, the control cabinet and the door of the high-voltage cabinet are mistakenly opened and to simultaneously remind the supervisor that someone exceeds the working range and needs to stopped in time. The alarm with the electrically controlled lock for preventing mistakenly entering the charged chamber has the advantages of simple structure as well as convenient installation and arrangement, and safely and highly efficiently achieves the purposes of preventing the workers from mistakenly entering the charged chamber, mistakenly touching the operating equipment and exceeding the working range.
Description
Technical field:
The mistakenly entering charged chamber alarm that prevents of band electric control lock of the present utility model belongs to sending out for the power transformation field of electric power system, and prevent mistakenly entering charged chamber and the mistake that relate in particular to a kind of active reminding alarm are bumped the alarm of the anti-super scope work of operational outfit.
Background technology:
Prevent that mistakenly entering charged chamber from being one of basic functions of transformer station's five-defence block of electric power system; the effect of playing that prevents staff's mistakenly entering charged chamber; guarantee that the staff works in the working range of safety; at present; electric power system prevent mistakenly entering charged chamber; mainly be to realize by electricity coding padlock; but; a lot of second protection screen and control cabinet are arranged; the cabinet door of high-voltage board; One's name is legion can't all be realized electricity coding padlock; owing to not having locking and can not initiatively remind reasons such as staff and guardian, the staff often occurs and surmount working range work and have an accident, or the malfunction mistake is bumped operational outfit electric shock etc.Therefore, press for a kind of active reminding alarm device of automation, prevent working member's mistakenly entering charged chamber, prevent that the malfunction operational outfit from surmounting working range, reduce operations staff's control in network system.
Summary of the invention:
The purpose of this utility model is to propose a kind of new, a kind of active reminding alarm of automation prevents the mistakenly entering charged chamber device, prevent working member's mistakenly entering charged chamber, prevent that the malfunction operational outfit from surmounting working range, reduce the instrument of operations staff's control.
The purpose of this utility model is achieved in that by magnetic relay unit, electric control lock unit, audible alarm chip and loudspeaker unit four parts to be formed, it is characterized in that: the control contact K1 of magnetic relay is arranged in the voltage circuit of electric control lock, and connects sound equipment alarm chip and and loudspeaker by electric control lock.The utility model can not be provided with wireless signal repeaters, and the control contact K2 of magnetic relay is arranged in the voltage circuit of wireless signal repeaters.The mistakenly entering charged chamber alarm that prevents of band electric control lock is a core with the magnetic relay control technology, cooperate realization monitoring personnel whether to surmount working range by electric control lock, the electric control lock key is preserved by the work permit people, when the people opens the work of cabinet door on the operational outfit of non-maintenance without approval, the magnetic relay action is connected sound equipment alarm chip and loudspeaker by electric control lock, sending alarm sound reminds the guardian to have the people to surpass working range, need in time to prevent, and remind the staff that mistake has been opened non-maintenance cabinet door.This device profile is simple, and outdoor location can install wireless signal repeaters additional, installing in 800 meters of distance master-control rooms, and the master-control room receiver can reliable reception be reported to the police.All use wireless signal, need not connect up, install simple.
The utility model is simple in structure, and installing is convenient, has solved safely and efficiently and has prevented working member's mistakenly entering charged chamber, prevents that the malfunction operational outfit from preventing to surmount the problem of working range.
Description of drawings:
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the schematic diagram that prevents the mistakenly entering charged chamber alarm of band electric control lock; K1, K2 are the control contact of magnetic relay.
Embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete execution mode according to the technical solution of the utility model and actual conditions.
Embodiment 1: when normally moving as Fig. 1; this alarm electric control lock is beaten to run location; this alarm electric control lock is beaten to overhauling the position during maintenance; the electric control lock key is preserved by the work permit people; when the cabinet door of people at the second protection screen of opening non-maintenance and control cabinet, high-voltage board; the magnetic relay action is connected sound equipment alarm chip and loudspeaker by electric control lock; sending alarm sound reminds staff's mistake to open the cabinet door of the second protection screen of non-maintenance and control cabinet, high-voltage board; remind the guardian to have the people to surpass working range simultaneously, need in time to prevent.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
