Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of switching device, and it is of compact construction and is suitable for the higher electric current of break-make.
According to the present invention, this technical problem is solved by a kind of switching device of multipole, and the switching device of this multipole is suitable for the heterogeneous electric loading of break-make and is equipped with at least one switch element for each switch pole,
-wherein said switch element has two switch contacts respectively, and
-wherein said switch contact can be separated from each other to disconnect respective switch element and can be connected to each other to connect respective switch element,
According to the present invention, switch element is spatially one after the other laid along the moving direction of switch contact.
A major advantage of the present invention is, because switch element is one after the other laid, between the electric arc of different switch elements, there will not be electric arc influence.Different from switch element layout side by side, in continuous switch element layout in succession, the spacing between electric arc is very large all the time, thus these electric arcs can not be interacted.Therefore other interval region need not be set between switch element to avoid electric arc adverse influence each other.
Another major advantage of the present invention is, switching device has very high make-break capacity, namely can the very large electric current of break-make, can realize in the version that space is crowded: make the diameter of single switch element with the make-break capacity that will reach, namely wanted break-make electric current and increase, thus when switch element is laid side by side, take up room and expand pro rata with the product of make-break capacity and number of poles substantially.When one after the other laying switch element according to the present invention, although the diameter of single switch element also increases, because switch element is one after the other laid, so the diameter of switch element is unimportant with the make-break capacity that will reach; When wishing that make-break capacity doubles, taking up room and only changing because of number of poles.Therefore also one very compact structure can be provided for the switching device with large make-break capacity.
If switching device is designed to circuit breaker and break-make can be carried out under load effect, be considered to favourable.
The switching device of multipole, preferably a kind of can the low voltage switching device of voltage in below break-make 1000V area of low pressure.When low pressure, the length of switch element can differently be designed to be relatively short with high-pressure area (more than 1000V), and it is especially favourable for thus longitudinally laying switch element.In addition, when low pressure, the electric insulation between switch element is relatively so unimportant, and thus with the cause for insulation aspect, the spacing between switch element must be designed to be larger high pressure difference, and switch element can be laid in succession by very dense ground.
Preferably vacuum switch element or vacuum switch tube are used as switch element.Described vacuum switch element can low pressure in the whole area of low pressure of below break-make 1000V.Consider the application in heavy current region, if the size of switch element be designed to respectively, make them often extremely can below break-make 10kA, preferred below 100kA or higher electric current, be considered to favourable.
That switching device is preferably three poles or four poles and often extremely preferably there is a switch element respectively.
At least one switch contact of each switch element, is preferably connected with a kind of connection contact that can get at from outside of switching device.Described connection contact is preferably mutual electric isolution.
According to the especially preferred expansion design code of one, each switch element has at least one dynamic switch contact, and described switch element is coaxially laid, and dynamic switch contact is in same mobile axis or same mobile axis moves along same mobile axis.This coaxial layout especially saves space-efficient.
If make a kind of operating element of such as rod-like be parallel to the mobile axis of switch contact and the liftoff laying of spacer with it, be also considered to favourable.Described joystick is preferably connected with the dynamic switch contact of all switch elements of multi-pole switching device indirectly or directly, and can move these dynamic switch contacts to switch on and off the pole of switching device.
If switch contact vertically deviates from the switch element that mobile axis extends be connected with a kind of respectively, be also considered to favourable.Belong to two contact elements of same switch element, preferably stagger mutually along the offset direction preset, make to form gap between two contact elements.
Described gap is preferably parallel to mobile axis and extends.This orientation in gap, makes it possible in described gap, such as lay a kind of mounting rail mechanically fixed or clamp switch element shell.The longitudinal axis of described mounting rail, the mobile axis being preferably parallel to switch contact extends.
As an alternative or supplement, the operating element of the above-mentioned switch contact for moving switch device can be laid in gap.
