Abstract
The utility model relates to a breaker, especially relating to an internal connection way of a four-pole leakage breaker. The connection way mainly comprises a zero-sequence current transformator, a breaker part and a connection wire sheet on the load end, wherein, the connection between the breaker part and the connection wire sheet on the load end adopts that rigid wires pass through the zero-sequence current transformator, the rigid wires means the copper details made by adopting mould shaping. The utility model is characterized in good interphase insulation performance, low temperature rising, easy realization of standardization, and convenient assembling.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of inner connecting way of four utmost point residual current circuit breaker.
Background technology
According to the direction of current low-pressure electronic equipment product to miniaturization, intelligent development, it is very compact that the position that makes circuit breaker that electric leakage element (connecting lead, zero sequence current mutual inductor, leakage circuit plate) is installed just becomes.All be to adopt cord to pass zero sequence current mutual inductor breaker portion is linked to each other (as shown in Figure 1) with the lug plate of load end at present in the residual current circuit breaker that each factory produces as the connection lead, every cord comprises the multiply annealed copper wire, this connected mode has the following disadvantages: (1) is because the pore size of zero sequence current mutual inductor can not be excessive under the qualification of installation site, thereby when passing four leads (i.e. a zero line, three live wires) simultaneously, just very crowded in the hole, almost there is not the space, radiating condition is bad, after the energising, temperature rise is higher; (2) four leads in the hole are in contact with one another together, and for the requirement of the phase insulation withstand voltage (2500V) that guarantees to reach prescribed by standard, every lead also must the thick insulating sleeve of cover last layer, therefore not only in the hole space littler, assembling is inconvenience extremely also; (3) when assembling, because the space is narrow and small in the hole, the friction between line and the line is comparatively violent, very easily damages insulating sleeve, produces phase fault.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of inner connecting way of four utmost point residual current circuit breaker is provided, this mode adopts cord that the formed in mould rigid line of sub-thread replaces being made up of the annealed copper wire of multiply as the connection lead, because under same current capacity, the rigid line of sub-thread is than the cross section of the annealed copper wire of multiply little (having the space) in the middle of the annealed copper wire of multiply, make the hole internal pore of zero sequence current mutual inductor strengthen, all gapped between each root lead, radiating condition is good, pass through air insulation, the every outer very thin insulating barrier of one deck that only needs of hard lead just can satisfy the phase insulation requirement of prescribed by standard, again because every lead is to make with die stamping, its high conformity is easy to assembling.
The utility model purpose realizes being finished by following technical scheme:
The utility model mainly comprises the lug plate of zero sequence current mutual inductor, breaker portion, load end, wherein adopt rigid line to pass zero sequence current mutual inductor between the lug plate of breaker portion and load end and is connected, described rigid line refers to the copper part that the employing mould molding is made.
The utility model has the advantages that the phase insulation performance is good, temperature rise is low, is easy to realize standardization, and is easy to assembly.
Summary of drawings
Accompanying drawing 1 is the utility model prior art schematic diagram;
Accompanying drawing 2 is the utility model structural representation;
Accompanying drawing 3 is a vertical view of the present utility model;
Concrete technical scheme
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
As Figure 1-3, always representing respectively in the accompanying drawing: zero sequence current mutual inductor (1), breaker portion (2), the lug plate (3) of load end, copper part (4) with reference to label 1-4.
The utility model mainly comprises the lug plate (3) of zero sequence current mutual inductor (1), breaker portion (2), load end, wherein adopts copper part (4) to pass zero sequence current mutual inductor (1) between the lug plate (3) of breaker portion (2) and load end and is connected.
In actual use, employed copper part (4) can be pressed actual needs according to the difference of circuit breaker model, makes difformity, size.
Claims (2)
1, a kind of inner connecting way of four utmost point residual current circuit breaker comprises the lug plate of zero sequence current mutual inductor, breaker portion, load end, it is characterized in that adopting rigid line to pass zero sequence current mutual inductor between the lug plate of breaker portion and load end is connected.
2, the connected mode of a kind of four utmost point residual current circuit breaker according to claim 1 is characterized in that described rigid line refers to the copper part that adopts mould molding to make.
