Description
Technical field
The present invention relates to the electrical breaks device (electrical interrupt apparatus) of circuit breaker type, this electrical breaks device is installed on the neutral line and at least one phase line or is installed on the many phase lines, and comprises the electronic circuit that at least one differential function (differential function) is provided.Device of the present invention can indistinguishably pass through top (top) or bottom (bottom) connects, and promptly the user can freely select to be connected to the side (side) of network.The connection custom of country variant even same country is different.
Background technology
So, must use various inspections and the test that described device is carried out under the same conditions to two kinds of possible connection types.Situation is such, for example, for the dielectric test of promptly being carried out between phase place (phase) and meta (neutral) from the opposition side of access network in the downstream (downstream) of device: no matter the downstream that is caused by selected network connection how, device must be set to conform to it.
In addition, for comprise differential function (as between phase place and the meta or the electronic circuit that between two phase places, is powered) product, international standard recommends to be provided with button, to allow people's test circuit.Standard in the enforcement can be implemented in institute and continue to push in the section of fixing time and electronic circuit is not caused any negative effects.This button is parallel to electronic circuit.
Can only from the conventional arrangement that a predetermined side connects,, make up at the fixing electronic circuit/testing button that is connected with the downstream of moving contact with respect to supply side for avoiding the wanton destruction risk.
Be economic cause, particularly in order to develop the single line product that can be used for two kinds of markets, a kind of can be conspicuous by the benefit of top and the device that promptly indistinguishably is connected by the interface unit that is present in both sides by the bottom.This is a purpose of the present invention.
Summary of the invention
For this purpose, the electric device of being developed generally includes:
Electronic circuit, this electronic circuit provide at least one differential function, are being powered between the neutral line and the phase line or between two phase lines;
Two interface units on each root line and a pair of fixing and moving contact respectively; With
The mechanical lock that discharges, this machinery discharges lock and comprises the moving contact supporting member, and the operated unit actuating,
The principal character of this electric device is, electronic circuit is that moving contact side on from described line one and the fixed contact side on other single line are connected.
The result is the crossfeed (crossed powering) to electronic circuit, and this provides the symmetry of a definite form from the viewpoint of indifference power supply.This intersection also solves above-mentioned variety of issue, particularly can be implemented in two kinds of connection hypothesis and carry out making testing button continue to remain closed in dielectric test and the scope at described circuit test between phase place and the meta down.
In addition, according to the present invention, extra switch be installed in and the junction and electronic circuit of phase line between, the opened/closed location-controlled of this extra switch and corresponding to the position of moving contact.
Use this switch, can between upstream and downstream, be applied to second dielectric test of this product, and can also under the situation that testing button is pressed, prevent to apply electromotive force (potential) to line downstream.
Its mechanical control piece that moves that passes through the contact (can realize reflecting the opening or make position of main contacts of circuit breaker) is such, be that it preferably closes and closure in the locking of machinery a little in advance, and lag behind opening of mechanical lock a little and open, to avoid by the caused risk that opens circuit arbitrarily of the electromagnet of for example electronic circuit.
Testing button is mounted to and resistor in series, and its combination is in parallel with electronic circuit.This so-called test resistor is set to adjust measuring current.Test resistor and extra switch are mounted to this fact of series connection, can be implemented in testing button and be disconnected the circuit of giving electronic circuit and circuit downstream power supply during continuing to press, thereby resistor is to the open-assembly time of measuring current.Therefore, restriction is through the energy of resistor.
Preferably, extra switch is supported the contact support actuating of at least one moving contact.In fact this feature can make moving of moving contact separate with the mobile of extra switch, does not feasiblely hinder and does not in fact reduce contact force.This switch all can not disturb the circuit breaker function in any case, the particularly important is the closure that it can not influence circuit breaker.
According to an operational feasibility, electronic circuit is by at least one printed circuit board (PCB) supporting.This configuration is explained apparent with regard to manufacturing be favourable, can be implemented in the integral body of implanting this circuit in the once-through operation, just as single component.
According to first replacement scheme, this switch is made of the compliant conductive bar, one of end of this conducting rod is fixed, and the other end is a free end, and this free end is driven into immediately after the moving contact closure with the conductivity guard shield door bolt (conductive shield latch) that is connected to electronic circuit and contacts.Perhaps, this can take place after opening moving contact immediately.
More specifically, so one of end of described compliant conductive bar may be attached to the printed circuit board (PCB) of supporting electronic circuit, another free end is driven into immediately with the conductivity guard shield latch that is fixed to described circuit board equally in the moving contact closure or after opening and touches.
Under these supposition, by the driving of the attaching part of moving contact supporting member is the free end of conducting rod.So this is processed to certain size, so that lax (relaxation) that the active force that is caused by rods is inducted do not influence the closure of extra switch.
Perhaps, but support (carriage) driving that this bar energy is moved by parallel-moving type, and this support overcomes back-moving spring by the moving contact supporting member and moves.
At electric device is that it comprises under the situation of bipolar (phase place-meta): the midfeather that breaker portion and electronic circuit are separated; This window is opened in the window in the described wall, so can guide the movable support of driving rods or the attaching part of contact support.
Under the supposition of support, the window that is opened in the wall can for good and all be interdicted by support, the passage between this difference shutdown device side and the electronic circuit side, and reduce the potential impact of a function to another function.
On the contrary, when directly driving, the part on the surface of described window remains open by moving contact supporting member (more particularly, the attaching part that this contact support moves in described window) when the conductivity rods, and this is influential to the circuit breaker function.May further become to pollute from that adnation of space of distributing to differential function.
