Abstract
The present invention relates to a display device for circuit breaker installations, especially for air and gas isolated medium voltage switchgears comprising the operational features 'connect', 'disconnect' and 'grounding'. The display device is formed by a diagrammatic representation (SB) covering nearly the entire surface on a protection panel (BA) closing the front contour of the circuit-breaker installation, wherein the circuit-breaker influences a circuit-breaker position display device (AL), the disconnector influences a disconnection position display device (AT), the cable grounder influences a cable grounding position display device (KA) and the bus grounding switch influences a bus grounding switch position display device (SA). Such display devices are used to monitor the operation of switch-breaking installation in energy supply and distribution.
Description
Technical field
The present invention relates to a kind of display unit that is used for breaker apparatus, especially for the display unit of the medium voltage switchgear equipment of air insulation, described equipment has " opening circuit ", " isolation " and " ground connection " function.
Background technology
The display unit of breaker apparatus is set directly in the opereating specification of switchgear in diversified mode.For example, at the HA.35.11.1996 of Siemens AG Representation catalogue, the the 16th and 17 page of (Katalog HA.35.11.1996, Seiten 16-17, show local circuit in three-point switch in the breaker apparatus of the 8DA 8DB series the Siemens AG) part and pluck figure, pluck figure by these circuit and as seen be used to the position of the three-point switch that drives and lock and the position of the switch of circuit breaker.In addition, the circuit in the three-point switch part is plucked also to illustrate among the figure and is used for the manually path to switch of control.
Summary of the invention
The technical problem to be solved in the present invention is, the demonstration of these known circuit diagram symbols is improved, and operating personnel can be looked with obscuring not see whole operating states, especially its operated device, demonstration and locking.
Above-mentioned technical problem is used to have " opening circuit " by a kind of, and the display unit of the breaker apparatus of " isolation " and " ground connection " function solves, according to the present invention,
1.1 display unit is made of one on the metal cover board that is positioned at close circuit breaker equipment front side plane circuit diagram symbol diagrammatic sketch,
1.2 circuit diagram symbol diagrammatic sketch has a circuit breaker position display unit that influenced by circuit breaker,
1.3 circuit diagram symbol diagrammatic sketch has an isolating switch lever position indicator that influenced by isolating switch,
1.4 circuit diagram symbol diagrammatic sketch has a cable grounding lever position indicator that influenced by the cable grounding cutter,
1.5 circuit diagram symbol diagrammatic sketch has a bus-bar ground connection cutter position display unit that influenced by bus-bar ground connection cutter,
1.6 isolating switch lever position indicator, circuit breaker position display unit and cable grounding cutter position display unit have electric current to pass through by a sign respectively or the demonstration lines of the rotatable setting that no current passes through are realized,
1.7 isolating switch lever position indicator and circuit breaker position display unit are arranged on the top of the cable grounding cutter position display unit of parallel access in a cluster.
Utilize the circuit diagram symbol diagrammatic sketch that constitutes on the whole faces in breaker apparatus front side that operating personnel are come into plain view to the whole operating state of breaker apparatus and unlikelyly obscure.
Further useful design of the present invention has following feature:
2.1 in isolating switch lever position indicator scope, be provided with a hand-control device and a locking device of being used for isolating switch,
2.2 in circuit breaker position display unit scope, be provided with circuit breaker be used to switch on and off, the hand-control device of pretension energy storage spring and energy storage spring state show and the switch counter,
2.3 in cable grounding cutter position display unit scope, be provided with a hand-control device that is used to switch on and off and a locking device of cable grounding cutter.
The manual control that is used for isolating switch, circuit breaker and cable grounding cutter that employing is equipped with by function-and locking device, can avoid in practice owing to the not very clear operating personnel's that cause misoperation.
Further useful design of the present invention has following feature:
3.1 in the scope of bus-bar ground connection cutter position display unit, be provided with a hand-control device that is used to switch on and off and a locking device of bus-bar ground connection cutter.Therefore circuit diagram symbol diagrammatic sketch also comprises the state of bus-bar ground connection cutter and operated device thereof.
Description of drawings
The present invention is described further will to contrast the embodiment shown in the accompanying drawing below.
Figure 1 shows that the display unit that is used for breaker apparatus according to the present invention.
Embodiment
Embodiment illustrates the metal cover board BA of breaker apparatus, and the whole plane of metal cover board is provided with circuit diagram symbol diagrammatic sketch SB.Circuit diagram symbol diagrammatic sketch SB is by isolating switch lever position indicator AT, and cable grounding cutter position display unit KA and bus-bar ground connection cutter position display unit SA constitute.As shown in FIG., isolating switch lever position indicator AT, circuit breaker position display unit AL and cable grounding cutter position display unit KA has electric current to pass through by a sign respectively and the demonstration lines of the rotatable setting that no current passes through are realized.Can see that in addition isolating switch lever position indicator AT, circuit breaker position display unit AL and cable grounding cutter display unit KA have handheld device and locking device that is used to switch on and off.SA also has this device to bus-bar ground connection cutter position display unit.
