Description
High voltage coupling contact
FIELD OF THE INVENTION The present invention is in the field of a high voltage coupling contact, and a system comprising such a high voltage coupling contact, such as a current collector, such as for a trolleybus, for a tram, for an electric locomotive, such as a pantograph, a trans-former, a power switch, a power divider, an earth contact, a high voltage station, an intermediate voltage station, and combinations thereof.
BACKGROUND OF THE INVENTION A high voltage coupling contract, such as that of fig. lc, typically are provided as a connection between two compo- nents. The contact is typically securely attached to the two components, such as by welding, by fixating, and so one. The contact typically is a single piece contact. The contact may be applied between an electric current collector, such as a pantograph, and a further component, such as an electric mo- tor and a transformer. The contact may likewise be used in electric power transmission, typically involving a high volt- age, typically above 1000 V AC or above 1500 V DC. High volt- age applications involve certain risks to humans and equip- ment, such as electrical arcing, sparking, and electric shock, and hence need to be dealt with precautions. Electri- cal transmission and distribution lines for electric power typically use voltages of 10-500 kV, so contact with or close approach to the line conductors presents a danger of electro- cution. A contact with overhead wires may cause injury and death.
Typically contacts are firmly attached to two components, such as by using bolts. As a conseduence, installation and replacement is risky and time consuming. In addition, after installation typically measurements (under load) need to be preformed in order to establish if for instance a contact is installed properly.
Therefore, there still is a need for an improved high voltage coupling contact, which overcomes one or more of the above disadvantages, without jeopardizing the essential func- tionality and advantages.
SUMMARY OF THE INVENTION The present invention relates in a first aspect to a high voltage coupling contact, basically comprising a male part, and a female part for receiving the male part, hence having at least two parts or pieces.
The present contact can be used as a connection between components.
It can be coupled and re- moved without the use of any further tool.
When installed a good contact is automatically obtained and no further meas- urement to establish if the contact is according to standards needs to take place.
This is considered a big advantage as a craftsman need not operate at a high voltage level in case of placement or replacement of components and contact.
The pre- sent contact can be applied as a separate part in a first or second component, such as a rail, or can be used as a quick coupling between two components.
It is considered a plug and play concept.
The present contact can be applied to high voltage components in advance (of use), therewith reducing installation time, such as at a construction, such as in the case of a high voltage power station.
The present contact is suited for nominal current transport and can withstand short currents that may occur in a high voltage net.
In addition, in use the female conducting materials provide a strong mag- netic field, which field provides a significant force applied on the contact between male and female parts, therewith keep- ing the male and female parts tightly in place, with respect to one and another, and with respect to the two components.
Said force can easily be 10% N, or much higher, depending on the current.
The contact can withstand high currents, such as 150 kA or higher, and likewise high voltages, such as 300 kV or higher.
The present contact can also be used as a quick releasable connection wherein components are at earth level, to ensure proper earth connection between two non-defined units; typically no current is then transferred, whereas a quickly releasable earth connection can be created.
It is noted that good earth connections in high voltages applica- tions are considered important as parts or components that are nor properly connected to earth can be charged as a sort of capacitor, by induction of surrounding parts that are un- der high voltage.
The present high voltage coupling contact (100), com- prises a male part (11), the male part comprising a central conductor (12), a male contact (13) provided at a top side of the central conductor, wherein the male contact is provided with a male conducting material (15%) at a surface thereof, and a connector (16) for removably attaching to a first high voltage component. It further comprises a female part (1), the female part comprising a receiving section (2) adapted to receive the male part, a contact section (3) adapted to be in electrical contact with the contact (13) of the male part, wherein the female part comprises at least two opposing con- ducting arms (4), wherein each arm is provided with female conducting material (5) at an inner surface thereof, a cur- rent transferor (7) in electrical contact with the conducting material (5) and conducting arm (4), and a connector (6) for removably attaching to a second high voltage component. The male part (11) is adapted to be removably contactable to the female part (1). Therewith the two parts can be connected easily and disconnected as well.
In a second aspect the present invention relates to a system comprising the present high voltage coupling contact, for transferring a high current.
Thereby the present invention provides a solution to one or more of the above-mentioned problems.
Advantages of the present description are detailed throughout the description.
