Abstract
The invention provides a kind of breaker with window, including case for circuit breaker, in addition to window, the window is transparent sheet-like；The case for circuit breaker includes left and right two parts；The groove consistent with the window external diameter is provided with the case for circuit breaker front end face；The window is connected and fixed with case for circuit breaker by the groove.A kind of breaker with window of the present invention can judge that dynamic/static contact whether there is failure by the window very first time on breaker, circuit breaker failure diagnosed in time after breaker open operation occurs.
Description
Technical field
The invention belongs to field of circuit breakers, more particularly, to a kind of breaker with window.
Background technology
Low-voltage circuit breaker is also known as air switch, can be substantially by saturating mainly for circuit is switched on or switched off under immunization with gD DNA vaccine
Viewing window is seen disconnection and closed a floodgate, convenient to repair locking function so as to play safety utilization of electric power or maintenance, makees circuit and power on
Or isolation is used.After low-voltage circuit breaker fault trip, it is impossible to which the combined floodgate of simplicity just terminates, and should first be observed.Because
The static contact of low-voltage circuit breaker, moving contact, spring, coil, etc. part all easily break down.By observing static contact scorch
Situation determines whether that static contact should be changed, in case polishing is excessive and reduces the pressure of contact surface；If moving contact goes wrong
Polished using fine sandpaper, contact surface there can not be greasy dirt.But all breaker can not occur for the circuit breaker on existing market
After tripping operation, the very first time judges that dynamic/static contact whether there is failure, and the diagnosis to circuit breaker failure produces delay.
The content of the invention
In view of this, the present invention is directed to propose a kind of breaker with window, can lead to after circuit breaker trip occurs
The window very first time crossed on breaker judges that dynamic/static contact whether there is failure, and circuit breaker failure is diagnosed in time.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of breaker with window, including case for circuit breaker, in addition to window, the window are transparent sheet-like；Institute
Stating case for circuit breaker includes left and right two parts；It is provided with the case for circuit breaker front end face consistent with the window external diameter recessed
Groove；The window is connected and fixed with case for circuit breaker by the groove；
Further, the window is square sheet；
Further, the two-part connected mode of described case for circuit breaker or so is to connect and fix.
Brief description of the drawings
The accompanying drawing for forming the part of the present invention is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate to be used to explain the present invention, do not form inappropriate limitation of the present invention.
In the accompanying drawings：Fig. 1 is a kind of breaker with window described in the embodiment of the present invention.
Description of reference numerals：
1- windows, 2- grooves, 3- left sides shell, 4- the right shell, 5- case noses face, 6- handles, 7- moving contacts, 8- connections
Bar, 9- static contacts, 10- shells.
Embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of breaker with window, including case for circuit breaker（10）, handle（6）, connecting rod（8）, moving contact（7）、
Static contact（9）, in addition to window（1）, the window（1）For transparent sheet-like；The case for circuit breaker（10）Including a left side（3）
And the right side（4）Two parts；The case for circuit breaker（10）On front end face（5）It is provided with and the window（1）The consistent groove of external diameter
（2）；The window（1）With case for circuit breaker（10）Pass through the groove（2）Connect and fix；The window（1）To be rectangular
Shape sheet；The case for circuit breaker（10）It is left（3）And the right side（4）Two-part connected mode is to connect and fix；Described handle（6）
It is hingeably secured to case for circuit breaker（10）On, and the handle（6）Pass case for circuit breaker front end face（5）Outer end；It is described disconnected
The moving contact of road device（7）, static contact（9）And connecting rod（8）To be arranged in parallel, when a short circuit occurs, the breaker utilizes
Electrodynamic repulsion force makes moving contact caused by short circuit（7）And static contact（9）Separate, handle（6）Separating brake.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
