An isolating switch (10) has a main sub-assembly (11) which is hung from an overhead power line prior to opposite ends of the isolating switch being permanently connected to the power line.
The container filled with insulator is provided with a window through which the contacts of the isolating switch can be observed.
The aim of the invention is to devise a disconnector (1) for switchgear which disconnector allows for a compact and space-saving design.
Either set of switches includes a disconnector I, a breaker I and a disconnector II connected in series.
A disconnector assembly (10) is provided for an arrester (13).
A disconnector assembly (10) is provided for an arrester (13).
The invention relates to switchgear (100) which has at least one circuit breaker or switch (107), an earthing switch (113) and a disconnector (105).
The upper isolator (2), the vacuum arc extinguishing chamber (12) and the lower isolator (18) are connected each other fixedly.
A signal is sent through the first galvanic isolator and received through the second galvanic isolator by the detection unit.
The output of the isolator (20) is connected to a complementary circuit (120) distant from the isolator via a fibre-optic cable (110).
Force transducers (80, 82) are connected between the isolator and the proof mass.
This conductor can advantageously form a moving contact (blade) (2) of a high-voltage isolator.
In the parameterization of electronic tripping devices of circuit breakers, an adjustment of the tripping device by unauthorized persons must be prevented.
This can be a load-break switch, whose phases are combined with cutouts, or a load-isolating breaker.
The conductor may form a mobile contact for a circuit-breaker.
A generator circuit-breaker disconnecting switch according to the invention has a compact structure.
A hook with a T-shaped hook end is provided on a load circuit breaker.
To achieve this, said connection elements comprise a disconnecting switch (4).
To achieve this, one of the disconnecting switches or each disconnecting switch (7) is located in an outdoor bushing (5).
The invention relates to a load-disconnecting switch with a permanent magnet holding circuit.
According to the invention, each bus bar conductor (3) is connected to a disconnecting switch (11) that is insulated by protective gas.
The load-disconnecting switch can be switched on again by means of a spring clip (12) that acts on the armature (6).
The interrupter switch (10) is part of a disconnect switch arm and is secured to the support housing.
The operation of the disconnect device can readily be seen.
The invention relates to the control of an electric switching apparatus that includes two switches such as a busbar sectionalising switch and an earthing switch.
In addition, a cutter cuts the transversal weld (7) thus produced and welds together the ends of the wrap on the one hand and the ends (5, 6) of the foils that can be drawn from the foil rolls (3, 4).
The invention also concerns a ground disconnect switch comprising such an assembly and a method for making a ground disconnect switch in accordance with the invention.
If necessary, the isolating link can be replaced by a switch connection.
A mechanical switching device which, in the open position, complies with the requirements specified for isolation.
The no-load switch is on a low voltage side of the transformer.
A shunt reactor (11) is connected to the isolated switch (13).
A mechanical switching device which, in the open position, complies with the requirements specified for the isolating function.
In other embodiments sensors having a local disconnect are disclosed.
When the disconnect switch closes, the latch lever (80) releases and the crank (57) rotates relative to the housing to operate the linearly movable rod (40) which operates the interrupter switch (10).
A switchboard section is equipped with a separating switch designed as a transformer switch.
A utility meter and a disconnect switch are installed at the customer premises.
Pipe cutting device (1) having a control valve (7) for actuating a slide valve (4).
