Problems solved by technology
[0002] The conventional way of current and voltage acquisition in the market at this stage is: each phase wears a current transformer and a voltage transformer, the transformer is fixed to the beam of the cabinet by screws, and the signal is uploaded through the wire. This method has the following aspects A problem: (1) Each current transformer is fixed by two screws, which is cumbersome to install and maintain; if the current transformer is damaged, it needs to be replaced again. If the screws are accidentally slipped off during replacement, it may cause short circuit of other components and damage the maintenance There are potential safety hazards for personnel; (2) Conventional current transformers on the market are large in size and not compact enough in structure; (3) There are many secondary lines of current transformers, which require high wiring technology and are not beautiful
If there is a problem with the wiring of the indicator light, it may affect the normal operation of the load
Due to the cumbersome process of connecting and fixing the indicator light, it brings a series of problems to its installation and maintenance: the wiring process of the indicator light is cumbersome, and the indicator light should be connected with a cable at the outlet of the circuit breaker (switch). Take power, so when installing or replacing the conventional indicator light, loosen the fastening screw of the terminal at the outlet of the circuit breaker (switch), then pull out or insert the cable, and finally tighten the screw to fix it. When the number of lamps is large, this wiring will consume a lot of time and manpower
As another example, routine indicator light replacement and maintenance may affect load operation problems
When replacing and maintaining, because the wiring needs to loosen the outlet terminals of the circuit breaker (switch), it is bound to cut off the load before wiring, which will affect the operation of the load.

Embodiment Construction
[0020] Such as figure 1 , 2 A device that integrates signal acquisition and indicator lights is shown, including a base 1, three bus bars, three current transformers 5 and their cover plates 10 arranged side by side on the base, indicator lights 6 and their cover plates 8. The current transformers 5 are all hollow square structures in the middle. The busbars include A-phase busbars 2, B-phase busbars 3 and C-phase busbars 4 arranged side by side. Each busbar passes through a current transformer 5. One end of the busbar is exposed outside the base 1, and the other end is fixed on the base 1 by screws.
[0021] In order to collect the voltage of each phase, the device that integrates signal collection and indicator light also includes three voltage mining lines (not shown in the figure), which are used to connect the current transformer and the busbar interspersed therein. One end of the line is connected to the N line through the internal PCB of the current transformer, and t...

The invention discloses a device for the integration for signal acquisitions and indicating lights. The device includes a base, a bus, a current transformer and a cover plate thereof and an indicating light and a cover plate thereof. The current transformer is in a square structure which is hollow in the middle. The bus penetrates through the hollow position of the current transformer. One end of each bus is exposed outside the base and the other end is fixed on the base through screws. The indicating light is fixed on the cover plate thereof through screw threads. Two electricity taking lines are fixedly arranged on the tail of the indicating light through screws. The two electricity taking lines contacts with any two buses in a one-to-one correspondence mode. The cover plate of the current transformer and the cover plate of the indicating light are fixed on the base in an upside down structure. The device has the advantages of modularity of current and voltage acquisitions and the indicating light, convenience to achieve corresponding insertions of output terminals and back board PCB (Printed Circuit Board), great secondary wiring reduction, compact integrated structure and convenient rapid safe installation and maintenance.
