The multifunctional automatic switch has the multifunction of over-load protection, short-circuit protection, under-voltage protection, electric leakage protection and back-up protection and has the advantages of small volume, convenient installation and maintenance and wide application scope. The utility model is especially suitable for the circuit protection of the countryside and the field work.
Description
The utility model provides a kind of multi-functional automatic switch, belongs to low voltage control equipment.
Present automatic switch, though have overload, short circuit and under-voltage protection, also can not connect continually and the function of branch deenergizing, but its protective device only adopts all kinds of tripper structures, the disjunction circuit performance is poor, is difficult to satisfy general selective protection, can not automatic closing, and inconvenience is installed, and wiring is particularly time-consuming and loaded down with trivial details; By the earth leakage protective screen that knife switch, fuse, A.C. contactor, earth leakage protective device, instrument transformer etc. are formed, then volume is big, heavy, cost is high, and noise is big and power consumption is many.
The purpose of this utility model is for overcoming above-mentioned weak point, and a kind of disjunction circuit performance is good, protection is reliable, handling safety, easy to use and provide, and automatic closing has the multi-functional automatic switch of automatic air-break switch and earth leakage protective screen function concurrently.
The purpose of this utility model is achieved in that backup protection equipment of serial connection in the connecting plate of plastic casing formula automatic switch, also has an automatic closing device in addition.
Accompanying drawing 1 is the utility model front view;
Accompanying drawing 2 is the left cutaway view of Fig. 1.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
Multi-functional automatic switch of the present utility model; the arc-extinguish chamber 1, the fixed contact 2 that comprise plastic casing formula automatic switch; connect that flexible cord 3, trip free device 4, handle 5, latch nook 6, return buckle 7, square shaft 8, heat thread off 9, hot dropout adjuster 10, wink moving magnetictrip 11, lower device conducting rod 12, binding post 13, base plate 14 and shell 15, it is characterized in that in connecting plate 16 one of serial connection is by fusible core 17, fusible core carriage 18, metal nuts 19, connecting rod 20 be enclosed within the backup protection equipment that the electric leakage instrument transformer 21 on the connecting rod 20 is formed.After fusible core 17 passes metal nuts 19, one end places on the fusible core carriage 18 that is fixed on the base plate 14, contact with connecting plate 16 epimeres, the other end is connected with metal nuts 19 by cover metal turn-knob 22 thereon, metal nuts 19 connects an end of connecting rod 20, and the other end of connecting rod 20 is connected with connecting plate 16 hypomeres folding shape.Above-mentioned parts refills shell 15 after being fixed on the base plate 14, and metal turn-knob 22 is in shell 15 panel precession metal nuts 19, and inspection hole 23 is left at its center, and handle 5 exposes outside shell 15, shell 15 corresponding binding post 13 places leaving certain gaps uncovered by the economic plans.The automatic closing device is by motor 24; electromagnetic brake device 25; bevel gear 26; 27; bearing pedestal 28; axle 29; cam hand 30 and controller 31 are formed; on side, shell 15 both sides a bearing pedestal 28 that is fixed on the base plate 14 is arranged respectively; connecting axle 29 between the two bearing bracket 28; corresponding handle 5 place's stationary cam hands 30 on axle 29; axle 29 1 ends are equipped with bevel gear 26; motor 24; controller 31 all is fixed on the base plate 14; be with electromagnetic brake device 25 in the middle of motor 24 output shafts; the fixing bevel gear 27 that is meshed with bevel gear 26 in end; the electromagnetic brake device 25 outer protective covers 36 that are equipped with; the two ends connection of electric leakage instrument transformer 21 has overload; short circuit; the input of the controller 31 of under-voltage and creepage protection function; its output is serially connected in the power supply input circuit of motor 24, on shell 15 panels leak(age) test knob 35 is housed.Artificial handle 32 is installed on the other end axle of motor 24, there is a thread circle hole at binding post 13 centers, one tension disc 33 is arranged at the bottom of the hole, and tension disc has wiring hole 33 times, will insert the connector lug of wiring hole by holding out against tension disc 33 behind the hold-down bolt 34 screw-in thread circle holes and fix.
The utility model is owing to adopt above design; in power supply circuits, be connected in series backup protection equipment; not only strengthened the disjunction circuit function; and improved the reliability of protection and the fail safe of operation, when maintenance circuit, power consumption equipment, fusible core 17 can be taken out; with anti-misoperation; guarantee job safety, and can observe the break-make situation of fusible cores 17 from inspection hole 23, easy to use.After increasing the automatic closing device, both solve the situation that DZ series 15A-100A automatic switch always can not electric switch-on, made it to have the function of earth leakage protective screen again.It is multi-functional that this automatic switch has overload, short circuit, under-voltage, electric leakage and backup protection simultaneously, and volume is little, install and maintenance convenient, widely applicable, the circuit protection that is particularly suitable in rural area and the field work uses.
