As a consequence, variations retaining devices are commonly used in an electric power distribution system to divert variations in overvoltage to the system floor, before variations in overvoltage can damage the electrical equipment connected to, or, the distribution system. of electric power. The typical variations retainer used in electric power distribution systems can fail in a runaway condition. When a fault like this occurs, the variation retainer can explode, potentially damaging nearby equipment and hurting anyone nearby. Therefore, it has been a common practice in the prior art to provide variation detectors with fault disconnectors, which open the circuits containing the faulty retainer. Usually, a fault disconnect is connected between its corresponding variation arrestor and the ground so that, when the fault disconnect is activated after the fault in the variation stop, the fault disconnect separates the retainer from variations of its connection to Earth. The separate ground connection not only disconnects the faulty varistor retainer from the power distribution system, but also provides a visible indication to a public utility line that has failed the & r retainer of variations. A typical fault disconnect includes a cartridge, which may contain a predetermined amount of gunpowder, and which heats up as the leak detector begins to fail. When the cartridge heats up enough, it explodes separating the retainer from variations in its ground connection. The amount of gunpowder used in the ceratucho is sufficient to cause that separation, but not enough to cause damage or injury. The cartridge, and the other elements of the fault disconnect, are contained within a housing of the cartridge that is a component separate from the variation retainer, having an intely threaded hole for the threaded joint with a housing of the variation retainer, and that has an exte threaded ground connector for connection to a ground terminal. An electrical resistor, which is another element of the fault disconnector and which is housed by the disconnect housing, is electrically connected between a terminal of the variation stop and the ground connector of the disconnect. In accordance with the above, when the variation stopper fails, the current through the electrical resistor increases abnormally and generates sufficient heat to activate the cartridge, causing it to break the disconnect housing and separate the ground terminal from the retainer of variations. The use of a separate disconnect housing increases the count of parts of a variation stop which, in turn, increases the manufacturing cost of the variation stop. The present invention is directed to a variation retainer that reduces the count of parts.
