Embodiment
Referring to figs. 1 through Fig. 3, the utility model surge protector embodiment is described further.
A kind of surge protector, comprise housing 1 and binding post 2, described housing 1 is provided with power supply 3, light-sensitive element 4, control circuit A, illuminating lamp LD and switch S; Described light-sensitive element 4 induction light line strength output detection signal; Described control circuit A is coupled to light-sensitive element 4, in order to receive detection signal and to export control signal; Described illuminating lamp LD is coupled to control circuit A, realizes the light on and off with light change, light, extinguish higher than during threshold value lower than during threshold value in order to responsive control signal; Described switch S is connected on the current supply circuit of control circuit A and illuminating lamp LD, in order to control the break-make of power supply 3.Power supply 3 can adopt electronics or cell device, circuit board is just arranged on housing 1, and control circuit A on circuit board, housing 1 secures illuminating lamp LD by glue, illuminating lamp LD is four in the present embodiment, as shown in Figure 1, because binding post 2 is multiple for having, four, the top binding post 2 of Fig. 1 connects three phase mains 3 and center line, for the binding post 2 of four-wire system, can pair of wire connection terminals 2 be thrown light on by four illuminating lamp LD, four illuminating lamp LD aim at the illumination of binding post 2 inlet wire respectively, four illuminating lamp LD are series connection, and light simultaneously, extinguish simultaneously.And the side of casing has been fixedly connected with light-sensitive element 4, light-sensitive element 4 is exposed to the external world, can respond to extraneous light conditions, can according to extraneous light conditions output detection signal, detection signal is the analog electrical signal of light, and light-sensitive element 4 can adopt photo resistance or light sensor.Control circuit A concrete structure illustrates below.The control that control circuit A can realize illuminating lamp LD light on and off by analog signal, can in rather dark, illuminating lamp LD be lighted, switch S is push-button switch S, switch S is as the starting switch S of control circuit A, the control signal that control circuit A exports can control lighting of illuminating lamp LD, realize illumination, make attendant still can carry out keeping in repair and changing components and parts in dim environment, thunderstorm weather, occur power-off and there is no light situation under, insufficient light is detected by light-sensitive element 4, undertaken lighting illuminating lamp LD by control circuit A again, be convenient to attendant and carry out maintenance process, the light on and off of automatic-control illumination lamp LD, very convenient.
As shown in Figure 2,3, control circuit A comprises sample holding unit A1, comparison circuit A2, performance element A3; Described sample holding unit A1 is coupled to light-sensitive element 4, in order to detection signal is converted to sampled signal; The circuit structure of sample holding unit A1 is illustrated in Fig. 2, analog signal is gathered by voltage follower circuit A1, by electronic switch SS1, electric capacity C1 is carried out from electric discharge simultaneously, thus analog signal can be made to be converted to discrete comparable sampled signal s1, thus it is more stable that circuit signal can be made to transmit, and avoids outside electromagnetic interference.
As shown in Figure 3, comparison circuit A2 is configured with a benchmark, and benchmark is can the threshold size of free setting, receives sampled signal and also exports comparison signal; Benchmark voltage is produced by potentiometer Rp1, the regulation and control of regulation benchmark can be realized by regulator potentiometer Rp1, thus can light illuminating lamp LD when that degree by light regulating, performance element A3 is coupled to comparison circuit A2, in order to receive comparison signal and to export control signal to control the light on and off of illuminating lamp LD.When sampled signal is greater than benchmark, its control signal exported of comparator is low level, otherwise the control signal exported is high level.
Performance element A3 comprises triode Q1 and relay K, the base stage of described triode Q1 couples the output of comparator, coil one end of relay K connects power supply 3, the collector electrode of other end connecting triode Q1, the grounded emitter of triode Q1, the normally opened contact of described relay K is series between power supply 3 and illuminating lamp LD.When push-button switch S is closed time, battery or electronics provide energy for circuit, now light-sensitive element 4 senses insufficient light, output detection signal, sampled signal is exported to comparator LM1 by sample holding unit A1, the voltage of the sampled signal that comparator receives is less than reference voltage, thus make triode Q1 conducting, relay K obtain electric after, connect the current circuit of illuminating lamp LD, thus illuminating lamp LD is lighted, for device illumination, if and in well-lighted situation, even if press the button switch S, illuminating lamp LD does not also work, thus there is energy-conservation effect.
Binding post 2 is provided with fluorescence block 5, and described fluorescence block 5 is fluorescent material.Fluorescence block 5 is the sides be adhesively fixed in the connection jaws of binding post 2, fluorescent material can send some faint light in the environment of dark, when dead battery, fluorescence block 5 can auxiliary light emission, thus device can be made safer in installation and maintenance process, it is more convenient to use.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
