Description
Technical field
The utility model relates to a kind of protective cover, particularly relates to a kind of switch cubicle control button protective cover.
Background technology
Switch cubicle control button is simple, the widely used miniature electrical equipment of a kind of structure, is mainly used to the short time to be switched on or switched off electric loop, realizes the control to electric loop, plays and important effect in electric power system.Because button is arranged on the panel of switch cubicle, control desk, control cubicle, under actual working environment, there is the situation of by mistake touching, cause deciliter circuit breaker by mistake, the safety of direct influential system, reliability service, under situation is serious, jeopardize personal safety.Switch cubicle is under charging operation condition, and operating personnel exists the situation of deciliter control button by mistake, causes the generation of power equipment accident.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
In order to solve the problem of deciliter control button by mistake, the utility model provides a kind of switch cubicle under charging operation condition, prevents the protective cover of deciliter control button by mistake.
The technical solution adopted in the utility model is:
Switch cubicle control button protective cover, it comprises in protective cover, protective cover along two pieces of bar magnets, sensitive switch and audible-visual annunciators installing, described protective cover is adsorbed on switch cabinet panel by bar magnet, described sensitive switch is installed in protective cover, described sensitive switch rely on the suction of magnet steel control sensitive switch contact deciliter, when protective cover is adsorbed on switch cabinet panel, sensitive switch contact disconnects warning circuit; When taking off protective cover, alarm circuit connected by sensitive switch, and audible-visual annunciator sends audio alert signal.
Described sensitive switch has push rod, dynamic circuit breaker shell fragment, break contact and Compress Spring, described push rod is used for masterpiece to be used for dynamic circuit breaker shell fragment, described dynamic circuit breaker shell fragment makes break contact quick-make or disconnection, described push rod lower end is connected with Compress Spring, contact-making switch cabinet panel bottom described Compress Spring, alarm circuit connected by described sensitive switch.
Described protective cover adopts transparent organic glass shell.
The beneficial effects of the utility model: protective cover is built with sensitive switch; control audible-visual annunciator; sensitive switch open circuit under normal circumstances; when taking off protective cover; alarm circuit connected by sensitive switch, and alarm sends audio alert signal, starts flash-caution function simultaneously; effectively can warn related personnel, prevent deciliter circuit breaker by mistake.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sensitive switch fundamental diagram of the present utility model.
Wherein: 1, audible-visual annunciator, 2, protective cover, 3, sensitive switch, 31, push rod, 32, dynamic circuit breaker shell fragment, 33, break contact, 34, Compress Spring, 4, bar magnet, 5, switch cabinet panel.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection range of the present utility model.
As shown in Figure 1, switch cubicle control button protective cover of the present utility model, it comprises in protective cover 2, protective cover 2 along the two pieces of bar magnets 4 installed, sensitive switch 3 and audible-visual annunciator 1, protective cover 2 is adsorbed on switch cabinet panel 5 by bar magnet 4, sensitive switch 3 is installed in protective cover 2, sensitive switch 3 rely on the suction of magnet steel control sensitive switch 3 contact deciliter, when protective cover 2 is adsorbed on switch cabinet panel 5, sensitive switch 3 contact disconnects warning circuit, this can allow circuit not consume electric energy under normal operating conditions; When taking off protective cover 2, alarm circuit connected by sensitive switch 3, and audible-visual annunciator 1 sends audio alert signal.
Shown in Fig. 2, sensitive switch 3 has push rod 31, dynamic circuit breaker shell fragment 32, break contact 33 and Compress Spring 34, push rod 31 is for being used for dynamic circuit breaker shell fragment 32 by masterpiece, dynamic circuit breaker shell fragment 32 makes break contact 33 quick-make or disconnection, push rod 31 lower end is connected with Compress Spring 34, be fixed on switch cabinet panel 35 bottom Compress Spring 34, alarm 1 circuit connected by sensitive switch 3.
The utility model installs a protective cover 2 on switch cubicle control button, is used for protecting control button.Protective cover 2 adopts transparent organic glass shell, be convenient to observe situation in protective cover, along installing two pieces of bar magnets 4 in outer cover, to be adsorbed on the panel of switch cubicle, cover, built with sensitive switch 3, controls audible-visual annunciator 1, under normal circumstances sensitive switch 3 open circuit, be fixed on switch cabinet panel 35 bottom Compress Spring 34, the break contact 33 of sensitive switch 3 is in off-state; When taking off protective cover 2; Compress Spring 34 pulls push rod 31; push rod 31 presses dynamic circuit breaker shell fragment 32; contact quick-make, alarm circuit connected by sensitive switch 3, and alarm sends audio alert signal; start flash-caution function simultaneously; effectively can warn related personnel, prevent deciliter circuit breaker by mistake, ensure that personal safety and the device security of operating personnel.
Along installing two pieces of bar magnets 4 in outer cover, the effect of bar magnet 4 had both been played and has been made protective cover 2 be adsorbed on effect on switch cabinet panel, can guarantee again to control the effect that sensitive switch 3 controls contact regular event.
Because button is arranged on the panel of switch cubicle, control desk, control cubicle, under actual working environment, there is the situation of by mistake touching, cause deciliter circuit breaker by mistake, the safety of direct influential system, reliability service, under situation is serious, jeopardize personal safety.Therefore, protective cover 2 must be increased on switch cubicle control button, avoid personnel to touch button by mistake, cause circuit-breaker switching on-off, find the effective countermeasure of removing a hidden danger, reach avoid power equipment accident to occur, ensure device security, reliable.
Switch cubicle is under charging operation condition, and protective cover can prevent deciliter control button by mistake, realizes protection operational outfit and warns related personnel, prevents deciliter circuit breaker by mistake, eliminates the potential safety hazard in running.It is simple that the utility model has structure, and the power work time is long, the advantage that reliability is high.And the production fields such as electric power system power transformation, distribution, rural power can be used in, improve the safety management level of whole industry.
