Abstract
Disclosed is an electric leakage circuit breaker integrated structure with electrophoresis protection, which solves the technical problem that an electrophoresis protector is installed on a three-phase leakage circuit breaker to form integration structure. Thus, four voltage-sensitive resistor installing frames are arranged at the middle of the bakelite base matched with the bottom of the breaker; the interlayer of the base soleplate is embedded an earth line brass plate and exposes five receiving line ends which are connected with the earth poles of the voltage-sensitive resistor and the outlet line of the earth line; one side of the installing frame is provided with receiving line ends which have the voltage-sensitive resistor outlet lines connected with the corresponding fuse and the inlet line end of the power supply, and the electrophoresis protector is fixed at the bottom of the leakage circuit breaker. The outlet line of the earth line is reliably connected with the earth by a grounding device. The utility model is suitable for single-phase three-phase leakage circuit breaker and other breakers, in particular uses in leakage circuit protection and lightning protection of the three-phase leakage circuit breaker.
Description
Technical field
The utility model relates to the residual current circuit breaker technical field, particularly a kind of charged residual current circuit breaker integral structure that gushes protection.
Background technology
Existing single-phase or three-phase residual current circuit breaker is that its power consumption equipment is carried out earth leakage protective, the three-phase residual current circuit breaker of industrial main employing three-phase four-wire system.Above-mentioned residual current circuit breaker itself does not have the lightning protection function; as lightning protection will be provided; have to go to choose one group of surge protector binding by the user and be contained in other vacant positions in the distribution box together; be connected with four line inputs of three-phase residual current circuit breaker by lead; thereby; trouble is installed, accounts for that the case area is big, poor stability, bring inconvenience to the user.
Summary of the invention
The technical problems to be solved in the utility model is: on the three-phase residual current circuit breaker, surge protector is housed, and becoming one structure.
The technical solution that the utility model proposed is such: a kind of charged residual current circuit breaker integral structure that gushes protection; comprise residual current circuit breaker and lightning-protection module 4; be provided with four lightning-protection modules at insulating base 1 middle part square frame 11 is installed; plot line copper coin 5 is hidden in the middle of pedestal 1 base plate; and expose ground wire terminals 8 in four installation square frame 11 1 sides of correspondence respectively; the opposite side of four installation square frames 11 is respectively equipped with independently terminals 3; four fuse 2 one ends respectively with power inleting terminal A; B; C; N is connected; its other end is connected with terminals 3 respectively; be embedded with lightning-protection module 4 respectively in described four installation square frames 11; its two electrode closely contacts with ground wire terminals 8 with corresponding terminals 3 respectively; ground wire lead-out wire 7 is connected with ground wire copper coin 5 by the 5th ground wire terminals 8; pedestal 1 is installed in residual current circuit breaker bottom, power inleting terminal A by the installing hole 6 that is positioned at four jiaos; B; C; N passes through screw; nut is connected with corresponding residual current circuit breaker power inleting terminal.Described lightning-protection module 4 is Zinc-oxide piezoresistor and/or discharge tube.When terminals 3 during, can be connected with fuse 2 one ends by lead-in wire copper coin 9 and the lead-in wire terminals 10 thereof that secretly bury away from fuse 2.The material of pedestal 1 can adopt thermosetting phenolic moulding powder or epoxy resin.
Compared with prior art, the utlity model has following beneficial effect:
Because surge protector and becoming one of residual current circuit breaker structure, thereby increased the lightning protection function of residual current circuit breaker; Its compact conformation, safe and reliable, easy for installation, duty is little, for the user brings convenience.
That the utility model is applicable to is single-phase, three-phase residual current circuit breaker and other circuit breakers, is specially adapted to the usefulness that the three-phase residual current circuit breaker is made earth leakage protective and lightning protection.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
By following embodiment the utility model is further elaborated.
Referring to Fig. 1, shown in Figure 2, a kind of charged residual current circuit breaker integral structure that gushes protection is made up of residual current circuit breaker and the surge protector that is packed in its bottom.This example is selected the three-phase residual current circuit breaker for use, is connected in the three-phase and four-line circuit.Thereby need be made the surge protection of every phase line with four Zinc-oxide piezoresistors 4; because this three-phase residual current circuit breaker bottom is a rectangle; so the pedestal 1 of the surge protector that matches also adopts rectangle; four used piezo-resistances 4 can only be arranged after two preceding two, thereby the terminals 3 of back two piezo-resistances 4 need to be connected with corresponding fuse 2 one ends by the terminals 10 that secretly are embedded in the lead-in wire copper coin 9 in the pedestal 1 and expose.If four piezo-resistances can be side by side and corresponding power inleting terminal A, B, C, the N of going up, then can cancel the lead-in wire copper coin.Four Zinc-oxide piezoresistors 4 are put into four installation square frames 11 respectively; the above round bar of the buried underground φ 16mm of a ground wire lead-out wire 7 and an end join the back just can make from external cable conduct the lightning current of coming in by surge absorbing directly to ground, protect power consumption equipment not to be damaged.
In this example, pedestal 1 is selected the compression molding of D161 thermosetting phenolic moulding powder for use, guarantees to have enough mechanical strengths, high performance dielectric strength, waterproof, protection against the tide, ageing-resistant.
It is 1.5mm copper plate electroplating surfaces with tin that ground wire copper coin 5 is selected thickness for use, is laid in the pedestal 1 bakelite base plate interlayer, has prevented oxide etch, only exposes 5 terminals 8 and joins for the grounding electrode ground connection of four piezo-resistances 4 and with ground wire lead-out wire 7.
