Abstract
The utility model provides an interlocking device with the priority of a grounding switch manual operation. The interlocking device comprises a travel switch with a normally closed node and a substrate. The substrate is fixed with a U shaped frame board whose opening faces a grounding switch operating hole. A sliding assembly capable of sliding left and right in the U shaped frame board is installed between the U shaped frame board and the substrate. The sliding assembly is in press fit with a button on the travel switch. A baffle plate capable of shielding the grounding switch operating hole is arranged at one side of the U shaped frame board on the sliding assembly. When the travel switch is in a free state, the baffle plate shields the grounding switch operating hole. When the travel switch is pressed, the baffle plate on the sliding assembly is removed to expose the grounding switch operating hole. The button is driven by the sliding assembly to cut off a grounding switch electric operation control loop, an electric operating mechanism is cut off when manually operating a grounding isolator, at the same time the baffle plate on the sliding assembly is removed to expose the grounding switch operating hole, and a grounding switch can be manually operated. A function with the priority of manually operating the grounding switch is realized, and threat to life of workers or generation of accidents due to misoperation is avoided.
Description
Technical field
The utility model relates to the safe operating mechanism of power switch cabinet, particularly the preferential interlock of a kind of earthed switch manual operation.
Background technology
Power equipment " five is anti-" is the abbreviation that prevents five kinds of electric misoperations in the electric power system, namely by mistake minute, mistake closes circuit breaker, on-load opening and closing isolating switch, band cable address (closing) ground connection burst at the seams (switch), band earth connection (switch) closes circuit breaker (isolating switch), mistakenly entering charged chamber.Therefore, the safety operation order that the necessary strict implement of various switchgear cabinets is certain, otherwise will cause serious consequence even accident occur.For this reason, switch cubicle should have " five is anti-" function.In recent years, increasing switchgear producer adopted motor-operating mechanism to control combined floodgate and the separating brake of ground cutter.If but because of reasons such as overhaul of the equipments or Installation and Debugging, need staff's manual operation switch cabinet ground cutter, and in the situation that motor-operating mechanism is not disconnected, this just might cause misoperation, cause accident to occur, even might jeopardize staff's life, for this reason, when carrying out manually cutter, motor-operating mechanism is cut off, i.e. manual operation is preferential carry out particularly important.
The utility model content
For addressing the above problem, the utility model is intended to propose the preferential interlock of a kind of earthed switch manual operation, cooperates to be grounded the preferential function of switch manual operation by slide block assembly and travel switch.
For reaching above-mentioned purpose, the utility model proposes the preferential interlock of a kind of earthed switch manual operation, contain the one stroke switch with normally closed node, it is characterized in that it also comprises: a substrate, fix an opening to the U-shaped deckle board of earthed switch handle hole at substrate, install between U-shaped deckle board and the substrate one can be in the U-shaped deckle board slide block assembly of move left and right, slide block assembly cooperates with button press on the travel switch; On slide block assembly
,U-shaped deckle board opening one side is provided with a baffle plate that can block the earthed switch handle hole; During the travel switch free state, baffle plate shelters from the earthed switch handle hole, and during the travel switch pressed state, baffle plate is stepped down to ground connection switching manipulation hole.
Fix a depression bar that cooperates with button press on the described slide block assembly, cover has one for the briquetting of pressing button on the depression bar.
Described depression bar is locked depression bar on slide block assembly by a screw.
After adopting technique scheme, the button of depression stroke switch when slide block assembly is stirred left, the baffle plate of slide block assembly is stepped down to ground connection switching manipulation hole, but earthed switch operating grip update hole operation; When the earthed switch handle hole does not have operating grip, and unclamp slide block assembly, the travel switch button flicks by the spring of self, and the drive slide block assembly moves right, the baffle plate of slide block assembly blocks the insertion that the earthed switch handle hole prevents the earthed switch operating grip, therefore, and when carrying out the earthed switch manual operation, earthed switch electric operating control loop is cut off by travel switch, realizes the preferential function of manual operation.
The beneficial effects of the utility model are: slide by slide block assembly and press the button of travel switch, cut off earthed switch electric operating control loop, motor-operating mechanism is cut off during cutter manually, baffle plate on the slide block assembly is stepped down to ground connection switching manipulation hole simultaneously, manual actuating earthed switch when ending, realize the preferential function of manual operation earthed switch, avoid causing misoperation and jeopardize staff's life or accidents caused.
