US Patent:

57903590, Aug 4, 1998

Filed:

Oct 17, 1997

Appl. No.:

8/953778

Inventors:

Wilhelm H. Kapp - Goleta CA
Manfred W. Wilms - Goleta CA

Assignee:

Joslyn Electronic Systems Corporation - Goleta CA

International Classification:

H02H 504

US Classification:

361106

Abstract:

A surge protection device comprising surge protector having a first terminal and a second terminal, one of the terminals being conductively connected to a first power transfer mechanism, such as a source of electrical power, and another of the terminals being conductively connected to a second power transfer mechanism, such as a sink of electrical power. The surge protector is operable to conduct current form one of the power transfer mechanism to another of the power transfer mechanism in the presence of a prolonged overvoltage surge across the first and second terminals of the surge protector. The surge protection device includes a mechanism for automatically disconnecting one of the terminals from one of the power transfer mechanisms in the presence of a prolonged overvoltage surge across the first and second terminals.

Wilhelm Kapp - Goleta CA
Ronnie Lee Bell - Santa Barbara CA

Assignee:

Joslyn Electronic Systems Corporation - Goleta CA

International Classification:

H02H 104

US Classification:

361118

Abstract:

An electrical surge protection apparatus is provided with first and second electrical terminals for connection to a first power line and third and fourth electrical terminals for connection to a second power line, a first conductive bus conductively connected to the first and second electrical terminals and a second conductive bus conductively connected to the third and fourth electrical terminals. Each of the conductive buses is sized to have a continuous current-carrying capability of at least about 60 amperes. The apparatus is also provided with a surge protector module having two terminals and a conductor which connects one terminal of the surge protector module directly to the first conductive bus and the other terminal of the surge protector module directly to the second conductive buss. The terminals of the surge protector module may be provided in the form of plug-in connectors, such as prongs, and the plug-in connectors may be plugged directly into a number of apertures or holes formed in the conductive busses.

International Classification:

H02H 320
H02H 906

US Classification:

361 56

Abstract:

The present invention provides a circuit for limiting voltage surges in load centers, panelboards and other electrical distribution devices. The circuit includes at least one high potential terminal adapted for connecting to at least one corresponding service line and a low potential terminal adapted for connecting to a low potential means. The circuit also includes a plurality of varistors connected in parallel to one another between each high potential terminal and the low potential terminal and a plurality of fuses corresponding in number to the plurality of varistors. Each fuse is connected in series to one of the varistors. Each fuse opens the circuit therethrough upon failure of the associated varistor. The circuit further includes monitoring the status condition of the fuses.

International Classification:

H02H 104

US Classification:

361127

Abstract:

A surge protector module is provided with a housing with an internal space, a separator disposed within the housing which divides the internal space into first and second spaces within the housing, and a surge protection device. The surge protection device has a surge protector mounted within the first space and a disconnect mechanism operable to conductively disconnect one of the terminals of the surge protector from one of the terminals of the surge protection device in the presence of a prolonged overvoltage surge across the terminals of the surge protector. A combustion-retardant material is disposed within the housing of the surge protector module so that it occupies only the first space within the housing, leaving the second space within the housing substantially free of the combustion-retardant material, and the disconnect mechanism is disposed in the second space in which no combustion-retardant material is disposed. Consequently, the presence of the combustion-retardant material does not interfere with the operation of the disconnect mechanism.
