Intelligent electricity meter.And small business develops rapidly and increased, the three-phase power consumption of small-sized electricity consumption user increases substantially, and is
Ensure tariff recovery rate, it is proposed that take control problem.
Existing three-phase and four-line metering cabinet primary clustering has housing, breaker of plastic casing, motor-operating mechanism, zinc oxide to take shelter from the thunder
Device, auxiliary reclay, electric energy meter, acquisition terminal, current transformer etc..Wherein electric energy meter, acquisition terminal, current transformer are by electricity
Power department provides.General electric energy meter metering electricity consumption, works as subscriber arrearage, and acquisition terminal remotely sends out separating brake instruction, auxiliary reclay line
Powered adhesive is enclosed, breaker closing becomes separating brake, and user is unable to electricity consumption；Such as subscriber payment, acquisition terminal releases separating brake instruction, middle
Relay circle is replied, and breaker closing, user can electricity consumption.This electric energy meter is commonly used in large and medium-sized electricity consumption user, alternatively referred to as
Dedicated transformer user, small-sized electricity consumption user using this scheme as that can increase fund input, and acquisition cost is higher, to power supply department
The operation that promotes the use add difficulty, so the three-phase and four-line 1.5*3 of small-sized electricity consumption user（6A）Take control table, alternatively referred to as public affairs
With transformer user, such as subscriber arrearage, expense control table built-in switch is not enough to disconnect user power utilization, can not ensure tariff recovery, because
This is, it is necessary to solve three-phase and four-line 1.5*3（6A）Expense control table effectively takes control problem.
The content of the invention
Problem to be solved in the utility model is three-phase and four-line 1.5*3（6A）Take control table small-sized electricity consumption subscriber arrearage without
Can be operated a switch power-off, there is provided one kind takes control case, and no expense automatically powers off, and effectively solves power department and is reclaimed for small electricity consumption demand charge
The problem of difficult.
In order to solve the above technical problems, the technical solution adopted in the utility model is：One kind takes control case, including casing, case
Control circuit is set in vivo, and control circuit meets three phase mains A, B, C by breaker inlet wire, and breaker outgoing line connects load, its feature
It is：The control circuit includes breaker of plastic casing, motor-operating mechanism, auxiliary reclay, auxiliary reclay coil, takes control
Table, opening button, switch knob；
The power supply A phase lines are respectively connected to the normally closed point of auxiliary reclay and opened point one end, the power supply A phase line access fees
Control the tripping operation common on table, described tripping operation normally opened contact access auxiliary reclay coil one end taken on control table, in described
Between another terminal connecting zero line of relay coil；
The power supply C phase lines access motor-operating mechanism common point, the normally closed point of travel switch in the motor-operating mechanism
One end of the normally closed point of auxiliary reclay is accessed, travel switch opened point access auxiliary reclay is normally opened in the motor-operating mechanism
One end of point.
Preferably, the opened point and opening button of the auxiliary reclay are in parallel, the normally closed point of the auxiliary reclay
Connected with switch knob.
The utility model utilizes three-phase and four-line 1.5*3（6A）Take control table tripping operation is public, relay among normally opened contact control
Device coil disconnects and adhesive, to realize small user's power failure and restore electricity, while realizes to user charge control function.
During normal operation, breaker one end access power supply, other end access load.
Instructed when three-phase and four-line takes control table hair separating brake, the tripping operation taken on control table is public middle with the normally opened closure that trips, access
Relay coil, the powered adhesive of auxiliary reclay coil, ZJ1 work, one group of normally closed point ZJ1-1 of auxiliary reclay is to normally opened
Point, another group of opened point ZJ1-2 to normally closed point, the opened point 3 of common point 1 and travel switch in motor-operating mechanism close,
The normally closed point 2 of common point 1 and travel switch is opened, motor-operating mechanism mechanical action（Fix a direction）, drive breaker
Separating brake cuts off user power utilization, and switch knob SB1 functions are invalid, and breaker will not close a floodgate.
Released when three-phase and four-line takes control table separating brake instruction, it is public with normally opened disconnection of tripping take tripping operation on control table, centre after
The no longer powered i.e. not adhesive of electric apparatus coil, ZJ1 are stopped, one group of opened point ZJ1-1 of auxiliary reclay to normally closed point, another
Normally closed point ZJ1-2 only need to close SB1 to opened point, user by switch knob, common point 1 and stroke in motor-operating mechanism
Switch opened point 3 disconnects, the normally closed point closure of common point 1 and travel switch, now by switch knob, motor-operating mechanism machinery
Action（Fix another direction）, drive short-circuiting device combined floodgate user can electricity consumption.
The utility model has the advantages and positive effects of：
1st, the utility model is connected using control table is taken with auxiliary reclay coil, takes control table hair separating brake instruction, middle relay
The powered adhesive of device coil, the opened point ZJ1-2 of auxiliary reclay to normally closed point form loop, and motor-operating mechanism is from closing position
Put open position, breaker open operation cut-out user power utilization, even if user is closed by switch knob manually, auxiliary reclay it is normal
Close point ZJ1-1 will not also close a floodgate to opened point, breaker, effectively control the power failure of arrearage separating brake, solve the small-sized electricity consumption of three-phase
User charge control problem.
2nd, the utility model is tripped using the tripping operation common of small relay in control table, tripping operation normally opened contact is taken,
Performed without manual button is needed.
3rd, the utility model takes control electricity box small volume, easy for installation, effectively solves the electricity of the small-sized electricity consumption user of three-phase and four-line
Meter amount and take control, equipment investment is few.
