Abstract
The utility model relates to a switch-on and switch-off display device of a flame-proof switch cabinet circuit breaker, which comprises a flame-proof switch cabinet door, wherein an observation window is arranged on the flame-proof switch cabinet door, and an instrument panel is fixed on the flame-proof switch cabinet door corresponding to the position of the observation window; the upper end of the instrument board is provided with an instrument board folding edge, the instrument board folding edge points to the outer side of the explosion-proof switch cabinet door, a double-color lamp band is attached to the lower surface of the instrument board folding edge, the double-color lamp band comprises a red lamp band and a green lamp band, the red lamp band is connected with an auxiliary switch-on contact of the explosion-proof cabinet circuit breaker, and the green lamp band is connected with an auxiliary switch-off contact of the explosion-proof cabinet circuit breaker. After the explosion-proof cabinet is installed and used, a field attendant can observe the on-off state of the circuit breaker of the explosion-proof cabinet at a distance, the working efficiency of the field attendant is improved, and the installation and wiring of the explosion-proof cabinet are extremely simple.
Description
Technical Field
The utility model belongs to the technical field of explosion-proof switch cabinets, and particularly relates to an opening and closing display device for a circuit breaker of an explosion-proof switch cabinet.
Background
The current on-off display of the circuit breaker of the explosion-proof switch cabinet mainly provides indication through a display panel matched with microcomputer protection. When the breaker is switched on, the red light emitting diode on the display panel is on; when the breaker is opened, the green light LED on the display board is on. The traditional display panel that is formed by the supporting protection of microcomputer provides the divide-shut brake can satisfy the operation requirement, but also has some problems, because the flame proof cubical switchboard observation window is little, can't see clearly from a distance which equipment moves, which equipment does not operate, and the personnel on duty need be close to equipment and carry out the operating condition who judges equipment from the emitting diode on the display panel in the observation window of equipment.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides the switch-on and switch-off display device of the circuit breaker of the explosion-proof switch cabinet, which is convenient for on-site operators to observe the switch-on and switch-off states of the circuit breaker of the explosion-proof cabinet at a remote place.
According to the technical scheme provided by the utility model, the switch-on and switch-off display device of the flame-proof switch cabinet circuit breaker comprises a flame-proof switch cabinet door, wherein an observation window is arranged on the flame-proof switch cabinet door, and an instrument panel is fixed on the flame-proof switch cabinet door corresponding to the position of the observation window;
the upper end of the instrument board is provided with an instrument board folding edge, the instrument board folding edge points to the outer side of a cabinet door of the explosion-proof switch cabinet, a double-color lamp band is fixed on the lower surface of the instrument board folding edge, the double-color lamp band comprises a red lamp band and a green lamp band, the red lamp band is connected with an auxiliary switch-on contact of the explosion-proof cabinet circuit breaker, and the green lamp band is connected with an auxiliary switch-off contact of the explosion-proof cabinet circuit breaker.
Preferably, the plane of the instrument panel folded edge is perpendicular to the plane of the instrument panel.
After the explosion-proof cabinet is installed and used, a field operator on duty can observe the on-off state of the circuit breaker of the explosion-proof cabinet at a distance, the working efficiency of the field operator on duty is improved, and the installation and wiring of the explosion-proof cabinet are extremely simple.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The present invention is further illustrated by the following examples.
The switch-on and switch-off display device of the flame-proof switch cabinet circuit breaker comprises a flame-proof switch cabinet door 1, wherein an observation window 2 is arranged on the flame-proof switch cabinet door 1, and an instrument panel 3 is fixed on the flame-proof switch cabinet door 1 corresponding to the observation window 2;
the upper end of instrument board 3 is equipped with instrument board hem 31, and the instrument board hem 31 points to the outside of explosion proof switch cabinet door 1, is equipped with double-colored lamp area 4 at the lower surface subsides of instrument board hem 31, double-colored lamp area 4 contains red lamp area and green lamp area, and red lamp area links to each other with explosion proof cabinet circuit breaker closing auxiliary contact, and green lamp area links to each other with explosion proof cabinet circuit breaker separating brake auxiliary contact.
The plane of the instrument panel folded edge 31 is perpendicular to the plane of the instrument panel 3.
After the explosion-proof switch cabinet breaker is used, when the explosion-proof switch cabinet breaker is in a closing state, the red lamp strip in the two-color lamp strip 4 is electrified and lightened, and the green lamp strip is not electrified; when the explosion-proof switch cabinet circuit breaker is in an opening state, the green lamp strip in the double-color lamp strip 4 is electrified and is lightened, and the red lamp strip is not electrified; therefore, the on-site attendant can easily observe the on-off state of the circuit breaker of the explosion-proof cabinet at a distance, and the working efficiency of the on-site attendant is improved.
