Abstract
The utility model provides a door opening audible and visual alarm system for preventing the forced door opening of medium/low-voltage equipment, wherein an operational power source is connected with a travel switch, and the travel switch is connected in series with an audible and visual alarm device. Compared with the prior art, the utility model can effectively warn the operator in both audible and visual ways in case that the cabinet door of the equipment is forcedly opened, so as to eliminate personal safety accident and hidden danger and ensure the safe operation of the power network in case of failure of the protective device of the equipment. In case of failure of the protective device of the equipment, the utility model can eliminate the safety accident and the hidden danger caused by the operator's faulty operations, such as negligent operation, customary operation and operation in the absence of the monitoring staff.
Description
Technical field
The utility model relates to a kind of acoustooptic alarm system that opens the door that is used to be furnished with the mesolow set of equipments of protective device.
Background technology
As national economy and the requisite secondary energy of people's lives---the carrying person of electric power energy, the mesolow set of equipments is extensively used, and is included in the factories and miness building in the big small-scale transformer station that implements the power transmission and distribution process, various fields, a large amount of residential quarters, commercial building etc.
And the extensive utilization of power equipment, provide electric power energy in development construction constantly for society, live for people's work offer convenience in, also be accompanied by threat to power industry staff personal safety.How to guarantee that personal security, safe operation of electric network become the problem that power equipment manufacturing firms are constantly explored.Nowadays, be equipped with safety device (using electromagnetic lock usually), structurally design the effect that aspect such as five-defence block reaches safeguard protection by the mesolow set of equipments both at home and abroad.But the security protection equipment that simple slave unit sets out and sets is comprehensive inadequately and hommization.Prior art can't effectively be warned operating personnel, because personnel's maloperations such as thin, off one's guard, the habitual operation of operator safety consciousness, nothing monitoring personnel operation often cause security incident.
Summary of the invention
The purpose of this utility model provides a kind of in being furnished with the mesolow set of equipments of protective device, under the situation that protective device suffers by force or pernicious destruction, equipment cabinet door are opened by force, still can prevent the mesolow equipment that opens the door the by force acoustooptic alarm system that opens the door to what operating personnel warned effectively by sound, light dual mode.
The technical solution of the utility model is: operating power is connected with travel switch, and travel switch is connected with the voice acoustic-optic alarm.
Described travel switch comprises moving contact, static contact, otherwise has the sheet metal that separates with static contact with static contact contact conducting warning system loop when equipment cabinet door is opened on the moving contact.
Described travel switch is installed on the equipment cabinet door column.
The described travel switch back of connecting with the voice acoustic-optic alarm is in parallel with electrification display, electromagnetic lock.
The police whistle sound of described voice acoustic-optic alarm is that the true man with hommization simulate caution sound: compare general chimes of doom on the one hand, the caution effect is more clear and definite, humanized; Be the sound that sends in view of the alarm that is equipped with in the difference transformer station on the other hand.
The photoelectricity form of described voice acoustic-optic alarm is the fast blink shape, from visually playing effective watchful effect.
In being furnished with protective device mesolow set of equipments, protective device suffers by force or pernicious destruction, and loses defencive function.Compared with prior art, even the utility model under the situation that equipment cabinet door is opened by force, still can be warned operating personnel by sound, light dual mode effectively, eliminate personal security accident potential, guarantee under the situation that the protective device of equipment lost efficacy electric power netting safe running.The utility model can be eliminated because operating personnel are off one's guard, habituation is operated, do not have the security incident hidden danger that personnel's maloperations such as guarding personnel operation cause under the situation of the protective device inefficacy of equipment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a scheme of installation of the present utility model.
The moving contact of the utility model travel switch and static contact position concerned synoptic diagram when Fig. 2 closed for equipment cabinet door.
The moving contact of the utility model travel switch and static contact position concerned synoptic diagram when Fig. 3 opened for equipment cabinet door.
Fig. 4 is a circuit diagram of the present utility model (when equipment cabinet door is closed).
Fig. 5 is circuit diagram of the present utility model (when equipment cabinet door is opened).
Among the figure, 1, operating power, 2, travel switch, 3, the voice acoustic-optic alarm, 4, moving contact, 5, sheet metal, 6, static contact, 7, lead, 8, electrification display, 9, electromagnetic lock.
Embodiment
Among Fig. 1, travel switch 2 is installed in the mesolow set of equipments of being furnished with protective device, operating power 1 is connected with travel switch 2, travel switch 2 is connected with voice acoustic-optic alarm 3 by the electric secondary line, voice acoustic-optic alarm 3 output signals, ring audio alert sound also sends the fast blink high light.Operating power 1 provides power supply for total system; when equipment normally moves; when the cabinet door is opened by force; travel switch 2 moves immediately; and transmit signals to voice acoustic-optic alarm 3 by electric secondary circuit; audio alert and photoelectric alarm signal were sent in action immediately after voice acoustic-optic alarm 3 received signal; make operating personnel still can in time obtain the open alarm signal; and then avoided the security incident hidden danger that causes owing to personnel's reason; from the omnibearing protection personal safety, guarantee safe operation of electric network.
Among Fig. 2, when equipment normally moves, when equipment cabinet door is closed, the moving contact 4(button of travel switch) by the door extruding, appended sheet metal 5 separates system circuit so access failure with sheet metal on the static contact 6 on the moving contact.7 is lead.
Among Fig. 3, when equipment cabinet door was opened by force, the moving contact 4 of travel switch was upspring automatically, and attached sheet metal 5 is connected with sheet metal on the static contact 6 on the moving contact, and system circuit is connected, the action of voice acoustic-optic alarm.
Among Fig. 4, Fig. 5, operating power 1 is connected with travel switch 2, and travel switch 2 back of connecting with voice acoustic-optic alarm 3 is in parallel with electrification display 8, electromagnetic lock 9.The utility model principle of work is: be equipped with the equipment of protective device electromagnetic lock safety device, under normal operation, the cabinet door can't be opened.When just when operating equipment cabinet door is opened by force, promptly the electromagnetic lock loop is cut off by force, causes function of safety protection to lose efficacy.But travel switch of the present utility model receives the signal of the action of opening the door, its junction closure.Form the closed-loop path this moment, and the voice photoelectric alarm device 3 on the loop move simultaneously immediately, and the audio alert sound that rings also sends the fast blink high light, maloperation warned, thereby effectively avoided the generation of security incident.
