Definitions
- the present invention relates to a device for pressure relief remote from the filling gas of a breaker.
- a circuit gas filling pressure relief comprising a switching chamber communicating with a block filling with dielectric gas and carried by a support frame, pressure relief device comprising a orifice passing through a wall of the circuit breaker and connecting the interior of the switch-off chamber and the exterior of the circuit breaker and a membrane closing this opening so waterproof and fixed to said wall by fixing members.
- this membrane commonly called rupture is arranged at one end of the chamber cut-off, at the top in the case of a cut-off chamber vertical. It is designed to burst when the internal pressure of the switching chamber reaches a certain value, corresponding to an operation faulty circuit breaker causing gas to heat up dielectric. This faulty operation is so general linked to a circuit breaker opening fault. The elimination of the membrane is therefore carried out automatically without human intervention.
- circuit breakers are increasingly equipped with advanced means of fault detection and control in the event of a fault, completing the use of a such a membrane.
- circuit breakers are increasingly equipped with advanced means of fault detection and control in the event of a fault, completing the use of a such a membrane.

- circuit breakers are increasingly equipped with advanced means of fault detection and control in the event of a fault, completing the use of a such a membrane.
- the invention provides a device for discharging pressure allowing manual intervention to dielectric gas pressure discharge, i.e. a dielectric gas pressure relief possible in all cases deemed necessary, and this is safe for the operator.
- the device according to the invention includes a member for eliminating said controlled membrane remotely.
- Said elimination organ may consist of an organ of destruction of said membrane or into an organ of destruction of said fixing members.
- said organ for destroying the wall may consist of at least one fusion arrangement partial of said membrane or in a needle arrangement striker mounted opposite said membrane.
- said organ for destroying fasteners may consist of an arrangement of fusion of these.
- the device is installed on the filling block.
- Figure 1 is a front view of a circuit breaker conventional with vertical breaking chamber.
- Figures 2 to 4 are views in horizontal section of the filling block of the circuit breaker of Figure 1, equipped of a device according to the invention.
- a conventional circuit breaker with breaking chamber vertical as described in Figure 1 has a support frame 1 on which a support case 2 is mounted in which is housed the transmission mechanism of control of the breaking chamber 3 supported by insulators 4.
- a grouping cabinet 5 contains the low voltage components, for example the monitoring.
- the block is arranged filling 6 as shown in FIGS. 2 to 4.
- This filling block 6 has a passage 11 for the dielectric gas filling the breaking chamber 3 with a first mouth 7 intended to receive a filling system, a second mouth 8 intended for receive a densistat type control device or pressure gauge, a third mouth 9 intended to receive an isolation valve allowing isolation of the chamber switch-off 3 in case of dismantling of the recording equipment and a fourth mouth 10 for communication with the breaking chamber 3.
- the gas pressure relief device filling comprises an orifice 12 passing through a wall of the filling block 6, connecting the interior of passage 11 and the outside and closed by a membrane fixed to the wall by fixing members, for example fixing screws, watertight thanks to seals.
- the device pressure relief device includes a device for eliminating the remote-controlled membrane, three variants of which are shown in Figures 2 to 4.
- the elimination organ may consist of a destruction of said membrane.
- a plate 16 fixed to the wall by screws 14, 15 and having a through bore 17.
- This bore 17 is closed by a membrane 13 made of fusible material, for example of fusible metal such as lead, in which is embedded a resistor connected to a remote control system. By connecting this resistor, the membrane 13 melts and is eliminated thereby allowing gas pressure discharge dielectric for filling through the bore 17.
- the wall's destruction organ consists of a firing pin arrangement mounted opposite a membrane 13 'formed in a plate 16' fixed on the wall by screws 14 ', 15'.
- the striker needle arrangement comprising a housing 20, for example cylindrical, in which is housed a needle 21 slidably mounted in a cylinder 23 fixedly mounted in the housing 20, biased by a compression spring 22 and retained in the non-active state by a retaining pawl retractable housed in cylinder 23.
- the elimination organ can also consist of a member for destroying fixing members.
- a plate or membrane 13 "closes the orifice 12 and is fixed to the wall by rivets 14 "and 15" in fusible material, by example in fusible metal such as lead, and in which a resistance is embedded connected to a control system remotely. From this system, by connecting the resistors, the 14 ", 15" rivets are melted, releasing the 13 "plate which falls and releases the orifice 12 through which the dielectric filling gas is evacuated.
