Abstract
A breaker operation device with a misoperation preventing function is composed of two-side disconnecting link and earthing knife-switch opened and closed auxiliary contact parts, a logic judgment part and a breaker control circuit part. Signals of the two-side disconnecting link and earthing knife-switch opened and closed auxiliary contact parts are input into the logic judgment part, the signals are output only when it is judged that all the input signals are in a state 1, and if not all the input signals are in the state 1, no signal is output according to the condition of an AND gate logic circuit. The condition is adopted as the switching-on condition of a breaker, a breaker control circuit closing coil circuit is connected, and the breaker is switched on. The breaker operation device is high in safety and convenient to operate.
Description
Technical field
ThisInventionPatent relates toA kind of have the breaker operating device preventing maloperation function。
Background technology
ThisInventionPatent relates toA kind of have the breaker operating device preventing maloperation function。
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention providesA kind of have the breaker operating device preventing maloperation function。
For achieving the above object, the technical solution used in the present invention is:A kind of have the breaker operating device preventing maloperation function, including both sides disconnecting link and the auxiliary contact part of grounding switch opening and closing state, logical judgment part, breaker control circuit part composition.The input logic judgment part of the auxiliary contact signal of both sides disconnecting link and grounding switch opening and closing state, judge that only input signal is all as the state of " 1 ", just there is output, if input signal is not all " 1 ", so condition according to AND gate, does not have output, in this, as the combined floodgate condition of chopper, connect breaker control circuit closing coil loop, it is achieved breaker closing.
The invention have the characteristics that
1, only having isolation switch in both sides closing position, both sides grounding switch is opening position, and chopper just can be operated.
2, the generation of misoperation fault is reduced.
Accompanying drawingIllustrate:
Fig. 1It it is the structural frames of the present inventionFigure。
Detailed description of the invention:
Such as Fig. 1Shown in:A kind of have the breaker operating device preventing maloperation function, form including by both sides disconnecting link and the auxiliary contact part of grounding switch opening and closing state, logical judgment part, breaker control circuit part.The input logic judgment part of the auxiliary contact signal of both sides disconnecting link and grounding switch opening and closing state, judge that only input signal is all as the state of " 1 ", just there is output, if input signal is not all " 1 ", so condition according to AND gate, does not have output, in this, as the combined floodgate condition of chopper, connect breaker control circuit closing coil loop, it is achieved breaker closing.
Operation principle:
(1) the auxiliary contact part of both sides disconnecting link and grounding switch opening and closing state.Reflection both sides isolation switch and both sides grounding switch opening and closing state, switch normally opened auxiliary contact both sides isolation and both sides grounding switch normally closed auxiliary contact access logical judgment part AND circuit.
(2) logical judgment part.Isolation switch in both sides is closing position, and its normally opened auxiliary contact are also closing position；Both sides grounding switch is opening position, and its normally closed auxiliary contact is closing position.The two input signal is all the state of " 1 ", and AND circuit just has output, as the essential condition of breaker closing.
(3) breaker control circuit part.The auxiliary contact input signal of both sides disconnecting link and grounding switch opening and closing state is all the state of " 1 ", just there is output, input signal as next stage AND circuit, now press switch knob, contact 5.-8. Continuity signal also serve as the input signal of next stage AND circuit, AND circuit just has output, it is achieved breaker closing.
Claims (1)
1. one kind has the breaker operating device that prevents maloperation function and is made up of both sides disconnecting link and the auxiliary contact part of grounding switch opening and closing state, logical judgment part, breaker control circuit part；The input logic judgment part of the auxiliary contact signal of both sides disconnecting link and grounding switch opening and closing state, judge that only input signal is all as the state of " 1 ", just there is output, if input signal is not all " 1 ", so condition according to AND gate, does not have output, in this, as the combined floodgate condition of chopper, connect breaker control circuit closing coil loop, it is achieved breaker closing.
