[0018] The utility model is further described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0019] Example 1
[0020] like Figure 1 and Figure 2 As shown, the utility model provides an embodiment of a three-phase electric automatic time switch safety protector, including a box body 1, wherein the box body 1 is provided with a three-phase switch 2, an AC contactor 3 and a timer switch 4, wherein the control end of the timer switch 4 is electrically connected to the coil of the AC contactor 3, and the output end of the three-phase switch 2 is electrically connected to the input end of the AC contactor 3 and the timer switch, respectively. The three-phase switch 2 is used to control the opening or disconnection of the lighting power supply. In the embodiment of the utility model, the three-phase switch 2 can adopt an air switch circuit breaker, or a circuit breaker with a leakage protection function. The embodiment adopts a DZ47L series leakage circuit breaker, which has a low cost, a breaking capacity, and a leakage protection function. The circuit breaker has the function of automatically tripping and powering off in case of electric shock or leakage. According to the lighting load requirements of the factory office building, a 100A leakage circuit breaker is generally used.
[0021] The box body 1 includes a bottom shell 11 and an upper cover 12, the upper cover 12 is hingedly connected to the bottom shell 11, a switch slot 13 and a timer slot 14 are provided on the upper cover 12, the three-phase switch 2 is fixed in the bottom shell 11, the three-phase switch 2 extends to the outside of the switch slot 13, and the panel of the timer switch 4 extends to the outside of the timer slot 14. In the embodiment of the utility model, the three-phase switch 2, the AC contactor 3 and the timer switch 4 are all installed inside the box body 1, and are fixedly connected to the bottom shell 11 by guide rails or bolt fasteners. The opening and closing operating handle of the three-phase switch 2 and the operating panel of the timer switch 4 are exposed on the outside of the upper cover 12 through the remaining switch slot and timer slot, which is convenient for personnel to operate.
[0022] The upper cover 12 is provided with a lock body 15, and the housing 11 is provided with a lock slot, and the lock body 15 is matched and connected with the lock slot. In the embodiment of the utility model, the box body 1 is provided with a lock body 15, which is used to lock the electrical components inside the box body 1 to prevent irrelevant personnel from intentionally damaging the utility model device.
[0023] The model of the timer switch 4 is a KG316T high-power time-controlled timer. In the embodiment of the utility model, the timer has six function keys: week, time adjustment, minute adjustment, timing, clock, cancel / reset (long press to unlock), and automatic / manual. The perpetual calendar can be set. Working days and non-working days, as well as working days, are set according to the needs of working days. The timer switch 4 is used to set the working period. For example, Monday to Friday, 7:30 am to 6:30 pm are set as working periods. The timer switch outputs a control signal to control the AC contactor 3 to turn on the output, so that the lighting load is powered on. In the period outside the working period, the timer switch 4 outputs a shutdown signal to control the AC contactor 3 to disconnect the output, so that the lighting load cannot be powered on.
[0024] The model of the AC contactor 3 is CJ20-100A / AC220V three-phase AC contactor.
[0025] The upper cover 12 is made of a polyethylene transparent plate.
[0026] The box body 1 has a height of 350 mm, a width of 300 mm and a depth of 65 mm.
[0027] Example 2
[0028] like Figure 1 and Figure 3As shown, the utility model provides another embodiment of a three-phase electric automatic time switch safety protector. The difference between the utility model embodiment and the embodiment 1 is that the control method of the lighting load during the abnormal working period is added, including a box body 1, wherein the box body 1 is provided with a three-phase switch 2, an AC contactor 3 and a timer switch 4, wherein the control end of the timer switch 4 is electrically connected to the coil of the AC contactor 3, and the output end of the three-phase switch 2 is electrically connected to the input end of the AC contactor 3 and the timer switch, respectively. The timer switch 4 is divided into two groups, and the control ends of the two groups of timer switches 4 are electrically connected to the coil of the AC contactor 3, respectively, and a human body induction switch 5 is arranged between the control end of one group of timer switches 4 and the AC contactor 3, and the human body induction switch 5 is electrically connected to the AC contactor 3 and the timer switch 4, respectively. In the embodiment of the utility model, the output ends of the two groups of timer switches 4 are connected in parallel and then electrically connected to the contactor control coil, and a human body induction switch 5 is arranged on the control circuit of one group of timer switches 4. When in use, for example, Monday to Friday, 7:30 am to 6:30 pm is set as the working period, and one group of timer switches 4 outputs a control signal to control the contactor 3 to turn on the output, so that the lighting load is turned on. Another group of timer switches 4 is set for non-working hours from Monday to Friday, that is, the abnormal working hours from 6:30 pm to 7:30 am, and the non-working days of Saturday and Sunday. During this period, another group of timer switches 4 is in the output mode, but at this time, the timer switch 4 cannot turn on the power of the lighting load. The lighting must be turned on when the human body sensing switch detects a human body signal. In this way, the lighting needs outside the abnormal working hours can be met, and it can be realized that someone can turn on the lighting load, and no one actively disconnects the lighting load.
[0029] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
