Problems solved by technology

However, this release has a very small pressure detection surface, so there are sensitivity issues in overpressure detection
To solve this problem and optimally capture the overpressure, the input orifice of the relief device is placed directly in the arc extinguishing chamber and traps the contaminated gas, which causes pollution management problems within the relief device

Embodiment Construction

[0055] refer to figure 1 and figure 2 , the pressure release device 1 according to a preferred embodiment comprises a housing 3 comprising two half-shells 3a, 3b which enclose an actuator 2 comprising a slave from the housing 3 protruding second end 13b. The half-shells 3a, 3b and the actuator 2 are preferably designed in a polymeric material in order to optimally support the hot gas G in a repeated manner without deformation. This is a release device that is considered "miniature"1.

[0056] The two half shells 3a, 3b have corresponding shapes and are joined to each other. They are preferably secured to each other by snaps: three snaps 4 are provided on the upper part (according to the arrangement of the release device 1 in these figures) and four snaps 4 are provided on the lower part. Such snaps make it possible to effectively close and seal the housing 3 .

[0057] The housing 3 thus closed can be added to the cut-off block of the line protection electrical equipment...

Abstract

A pressure-actuated tripping device for an electrical line protection apparatus, of the circuit-breaker type, delimited by an enclosure and comprising inside the enclosure: a gas inlet orifice openinginto an upstream chamber; a downstream chamber; an actuator that can rotate against a return means between a rest position and a tripping position, the actuator being positioned between the upstreamchamber and the downstream chamber and per se partially delimits the upstream chamber and the downstream chamber.

Description

technical field [0001] The invention relates to a pressure release device for line protection electrical equipment. The invention also relates to a circuit breaker type line protection electrical device comprising such a pressure relief device. [0002] The invention relates more particularly to so-called "instantaneous" or "reflective" releases, which increase the speed of release of such devices, thereby improving the efficacy of the product in its primary protective function, and from the grading achieved by conventional circuit breakers From the management point of view of site protection, it is possible to improve coordination / selectivity with other circuit breakers present in the same circuit. [0003] The invention in fact makes it possible to adjust the response time of a circuit breaker, and thus its level of operation, relative to the release times of other circuit breakers in the same circuit. [0004] Electrical equipment of the circuit breaker type, on which an ...
