Description
Technical field
The utility model relates to a kind of distribution box, is specifically related to a kind of distribution box with pre-payment management function.
Background technology
At present, the master switch of some power consumer switchgear houses does not possess trip avoidance function, electricity charge automatic trip function is owed in very difficult realization, the measure of generally taking is at present change master switch and install stuffing box additional, change horizontal batch meter and even change the way of always manipulating stock quotations, difficulty of construction is large, expense is high, the engineering time and interruption duration long.After user is had a power failure, some user can power transmission maybe dare not operate, and also needs power supply management personnel to go to, and has wasted manpower financial capacity, has affected user's production.The a few thing of user on always manipulating stock quotations, must first to high-tension apparatus, have a power failure, and user's majority can not operate high-tension apparatus, has affected production.
Summary of the invention
The utility model for address the above problem provide a kind of can be used as normal circuit breaker stop power transmission, can realize arrearage tripping operation again, pay the fees after the distribution box with pre-payment management function of automatic switching-in function, reduce user's operation, improve the convenience of user management.
The utility model is that the technical scheme that technical solution problem adopts is:
Distribution box with pre-payment management function described in the utility model comprises casing, is arranged on circuit breaker and ammeter in casing, in the inner chamber of described casing, is provided with diaphragm plate, in the casing of diaphragm plate top, fixedly mounts circuit breaker, ammeter and combined floodgate indicator light, in the casing of diaphragm plate below, be installed with the first auxiliary relay, the second auxiliary relay, opening button, switch knob, the coil of often driving idle contact and the first auxiliary relay of described ammeter is connected on the major loop forming between the live wire of supply line and zero line, the normally-closed contact of described the first auxiliary relay opening button of connecting successively, switch knob, the coil of the second auxiliary relay forms subloop, described subloop is connected in parallel on the two ends of major loop, first pair of normally opened contact of described the second auxiliary relay is connected in parallel on the two ends that idle contact often left by ammeter, one end of second pair of normally opened contact of described the second auxiliary relay is connected to the common port that the normally-closed contact of idle contact and the first auxiliary relay often left by ammeter, the other end is connected to the common port of opening button and switch knob.The two ends of described combined floodgate indicator light connect respectively the power end of the normally-closed contact of the first auxiliary relay and the common port of opening button and supply line.
Owing to having adopted said structure, this distribution box is used for being arranged between power consumer transformer and distribution board, not only can effectively realize the function of arrearage tripping operation, also realized pay the fees after automatic switching-in function, difficulty of construction is little, expense is low, engineering time and interruption duration significantly shorten, the work load that has alleviated power supply management personnel, has guaranteed user's production better.Meanwhile, when not arrearage of user, the divide-shut brake button that user can also operation control box stops power transmission normally, has solved the difficult problem that the upper work of always manipulating stock quotations must first have a power failure to high-tension apparatus.Diaphragm plate is the component classification setting of different purposes in distribution box, user-friendly and observe.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the electrical block diagram of an embodiment of the utility model.
Embodiment
As shown in Figure 1, distribution box with pre-payment management function described in the utility model comprises casing 2, is arranged on circuit breaker 1 and ammeter 3 in casing 2, on the sidewall of casing 2, can also pass through hinge mounting door plate 5, in the inner chamber of described casing 2, be provided with diaphragm plate 4, in the casing of diaphragm plate 4 tops, fixedly mount circuit breaker 1, ammeter 3 and combined floodgate indicator light LED; In the casing of diaphragm plate 4 belows, be installed with the first auxiliary relay, the second auxiliary relay, opening button T1, switch knob T2.Need ammeter 3 and the unified top that is arranged on casing 2 of combined floodgate indicator light LED of routine observation, be convenient to observation; By do not need often operation minute, switch knob is arranged on the below of casing 2, be hidden in door-plate 5 after, can avoid misoperation.
As shown in Figure 2, the coil J1 that often drives idle contact T3 and the first auxiliary relay of described ammeter 3 is connected on the major loop forming between the live wire L of supply line and zero line N, connect the successively coil J2 of opening button T1, switch knob T2, the second auxiliary relay of the normally-closed contact CJ1 of described the first auxiliary relay forms subloop, opening button T1 adopts and often drives button, and switch knob T2 commonly uses normally closed button.Described subloop is connected in parallel on the two ends of major loop, first couple of normally opened contact CJ21 of described the second auxiliary relay is connected in parallel on the two ends that idle contact T3 often left by ammeter, and one end of second couple of normally opened contact CJ22 of described the second auxiliary relay is connected to ammeter and often drives the common port that common port, the other end of the normally-closed contact CJ1 of idle contact T3 and the first auxiliary relay are connected to opening button T1 and switch knob T2.Described circuit breaker 1 adopts CD2 electricity behaviour circuit breaker; The first described auxiliary relay, the second auxiliary relay all adopt HH52P type auxiliary relay.
In addition, between the normally-closed contact CJ1 of the first auxiliary relay and the common port of opening button T1 and the power end of supply line, be provided with combined floodgate indicator light LED, for the operating state of indicating circuit directly perceived.
One of utilizing ammeter to provide of the utility model often opens idle contact T3, when user owes electricity charge space-time junction closure, starts the first auxiliary relay, the normal opened contact of the first auxiliary relay starts the trip(ping) circuit of circuit breaker 1, user's power-off, switch knob 4 upside power-off, circuit breaker 1 closes not brake application; When user has handed over after the electricity charge, ammeter normal opened contact disconnects, and the normally-closed contact CJ1 of the first auxiliary relay starts, circuit breaker 1 automatic closing power transmission, and the indicator light LED that simultaneously closes a floodgate lights.
During not arrearage of user, press opening button T1, start the second auxiliary relay, first couple of normally opened contact CJ21 of the second auxiliary relay is closed, start the first auxiliary relay, the normal opened contact of the first auxiliary relay is connected circuit breaker 1 trip(ping) circuit, circuit breaker trip, second couple of normally opened contact CJ22 of the second auxiliary relay forms self-sustaining, guarantees that circuit breaker 1 is all the time at open position; When pressing switch knob T2, the second auxiliary relay dead electricity, the normal opened contact of the second auxiliary relay disconnects and makes the first auxiliary relay dead electricity, and the normally closed contact of the first auxiliary relay is connected circuit breaker 1 trip(ping) circuit, circuit breaker 1 tripping operation.
This embodiment can realize arrearage tripping operation, automatic switching-in function after paying the fees; Can be used as normal circuit breaker and stop power transmission.
