The purpose of this utility model is by the structure of existing DZ47LE-32 plastic enclosure leakage circuit breaker is improved; overcome the above-mentioned defective that prior art exists; a kind of novel plastic enclosure leakage circuit breaker is provided; model is DZ479LE-32; its good looking appearance, volume is little, low cost of manufacture; and guarantee protection to circuit, safe in utilization.
For achieving the above object; the solution that the utility model is taked is: a kind of novel plastic enclosure leakage circuit breaker; the disconnection protection system and the leakage protection system that comprise protected circuit; the disconnection protection system of protected circuit comprises breaker contact system; arc control device; electromagnetic system and drive system; drive system comprises handle; tripping; lever; the interlock spring; the U-shaped axle; leakage protection system comprises the detection current transformer; magnetictrip; the electronics amplifying circuit board; leak(age) test mechanism; its feature is in pedestal; protecgulum; bonnet is formed a housing, and the disconnection protection system and the leakage protection system of protected circuit are installed in the described housing.
The utility model is installed in the disconnection protection system and the leakage protection system of protected circuit in the housing, compares with DZ47LE-32, and simple and reasonable, volume is little, good looking appearance, and reduced manufacturing cost.
Below in conjunction with embodiment and accompanying drawing thereof the good effect of the utility model and generation thereof is remake description.
Fig. 1 is the front view after present embodiment removes protecgulum 15.
Fig. 2 is the vertical view of present embodiment.
Fig. 3 is the left view of present embodiment.
Fig. 4 is the rearview after present embodiment removes bonnet 12.
Among the figure: 1, arc control device, 2, electromagnetic system, 3, snap close, 4, the interlock spring, 5, dead man, 6, pedestal, 7, handle, 8, tripping, 9, lever, 10, the U-shaped axle, 11, breaker contact system, 12, bonnet, 13, the electric leakage indication piece, 14, test button, 15, protecgulum, 16, zero line fixed contact assembly, 17, the zero line moving contact component, 18, the dead man spring, 19, fork, 20, the test contact, 21, button spring, 22, conducting strip, 23, the fork spring, 24, electric leakage indication piece spring, 25, magnetictrip, 26, detect current transformer, 27, the electronics amplifying circuit board.
As Fig. 1～shown in Figure 4; a kind of novel plastic enclosure leakage circuit breaker; the disconnection protection system and the leakage protection system that comprise protected circuit; the disconnection protection system of protected circuit comprises breaker contact system 11; arc control device 1; electromagnetic system 2 and drive system; drive system comprises handle 7; tripping 8; lever 9; interlock spring 4; U-shaped axle 10; leakage protection system comprises detection current transformer 26; magnetictrip 25; electronics amplifying circuit board 27; leak(age) test mechanism; its feature is in pedestal 6; protecgulum 15; bonnet 12 is formed a housing, and the disconnection protection system and the leakage protection system of protected circuit are installed in the described housing.
As shown in Figure 3; also be provided with a protection system that the zero line of protected circuit is disconnected in the leakage protection system; be provided with zero line fixed contact assembly 16 and zero line moving contact component 17 in this system; zero line moving contact component 17 is stuck in the dead man 5 as contact supporting; dead man 5 and a fork 19 interlocks; dead man 5 contacts with a dead man spring 18, and fork 19 contacts with a fork spring 23.The utility model is compared with existing DZ47LE-32, has increased a protection system that the zero line of protected circuit is disconnected, and has guaranteed the protection to circuit, uses safer.
As shown in figures 1 and 3, the dead man 5 one ends dividing wall that passes pedestal 6 contacts with snap close 3.Because snap close 3 and tripping 8, lever 9, U-shaped axle 10 and handle 7 etc. are interlock mutually; and dead man 5 and fork 19 and zero line moving contact component 17 interlock mutually; therefore a reset operation of handle 7 just can be connected protected circuit; the disconnection protection system homing action and the leakage protection system homing action of protected circuit are combined; simplified reset operation, avoided fault and judge the phenomenon that fault do not get rid of by accident and occur.
