Detailed Description of the Embodiments
[0022] Before explaining the present apparatus in detail, it is to be understood that the apparatus is not limited to the particular embodiments and that it can be practiced or carried out in various ways.
[0023] The present embodiments relate to a framed robot for charging, closing, or tripping electrical equipment within a hazardous arc flash zone.
[0024] This device enables an operator to be a safe distance from gear in an electrical room so that the operator is not harmed if arcing or shocks occur.
[0025] The device can include simple components and can require no special training to operate.
[0026] The device can be portable and lightweight, for example the device can weigh less than fifty pounds.
[0027] The device can charge, close, or trip a circuit breaker without drilling holes in the electrical equipment.
[0028] The device can be used to charge, close, or trip any variety of DS circuit breakers thereby allowing a user to be able to purchase one device for use with all of that user's circuit breakers. For example, a refinery might have any where from 3 to 50 different DS style circuit breakers. That refinery can purchase and use a single device to charge, close, or trip every DS style circuit breaker at the refinery. There is no longer a need to provide individual charge, close, tripping devices that are permanently affixed over each circuit breaker.
[0029] The device can reduce the cost of maintenance of circuit breakers.
[0030] Users of the device can include but are not limited to operators in chemical plants, hospitals, hotel electrical rooms, and other electrical areas with switch gear and circuit breakers.
[0031] The device can effectively remove the operator from immediate danger from arc flashing. The operator can be completely out of the arc flash zone.
[0032] Operators of the device can be typically from about ten feet to about twenty five feet away from the circuit breaker or electrical equipment being charged, closed, or tripped, thereby preventing electrical shock of the operator.
[0033] The device can reduce a facility's need to buy as much high level protective equipment, allowing the facility to procure lighter-weight personal protective equipment that is not as hot, heavy, or as likely to cause heart attacks in wearers.
[0034] The use of the device can lower costs to a facility by a service company or owner of the facility, because the facility can avoid purchasing as many expensive high level shock arc flash safety suits.
[0035] Use of the device can reduce liability to a user because of the reduced exposure time in the arc flash suits due to the quickness of the mechanized charge, close, or trip.
[0036] The present embodiments relate to a charge, close, trip device with a solenoid on a frame that can be made from aluminum channel, lightweight reinforced plastic, or reinforced composites.
[0037] The frame can include supports. For example, the frame can include a first side support which can have a first side support front side.
