It closes, so that different electric elements is connected, form the Acquisition Circuit of required voltage class, to control the switching of data gather computer structure
After to corresponding voltage class, then acquire related data.
But due to be likely to occur user select mistake situation so that user's selected voltage grade be actually subjected to supervise
The voltage class of the circuit of control is not met, and is easily damaged arc extinguishing type protective device, therefore, in the present embodiment, when magnetic induction loop 109
It is electric after, control chip 102 can also determine the voltage class of current line according to the electriferous state of magnetic induction loop 109, and
Corresponding voltage selection instruction is generated, the corresponding voltage of voltage selection instruction is switched to automatically control the selection of selecting switch 114
Grade improves arc extinguishing type protective device self-security.
During specific implementation at one, as shown in figure 3, the arc extinguishing type protective device of the present embodiment can also include data
Set up an organization 115.Wherein, data set up an organization 115 with control 102 signal of chip connect.In practical applications, due to electricity consumption height
Peak phase, different circuit use the factors such as object difference so that different periods, different circuits monitoring requirement may be different, because
This, the present embodiment can targetedly go monitoring circuit operation conditions, to improve monitoring efficiency, reduce arc extinguishing type protective device
Operation power consumption etc..Specifically, user can input relevant acquisition parameter, and set up an organization and 115 will receive by data
Acquisition parameter be sent to control chip 102, to make control chip 102 according to acquisition parameter control the first data gather computer structure
101 acquisition related datas.
For example, in the present embodiment, acquisition parameter may include but be not limited to the corresponding frequency acquisition of different time and/or
The acquisition priority level of different circuits.The peak times of power consumption of a certain circuit corresponding time can be known according to practical experience, this
When can be within the period, when being acquired related data rather than peak times of power consumption according to higher frequency acquisition, can be by
Related data is acquired according to lower frequency acquisition, to reduce the operation power consumption of arc extinguishing type protective device.It can also be according to reality
The acquisition priority level of empirically determined difference circuit, for example, the supply object of circuit A is relatively important, and the supply object of circuit B
It is relatively secondary, at this point it is possible to circuit A is provided with preferential collection, and circuit B is set as acquiring again after circuit A acquisitions finish,
It no longer illustrates one by one herein.
As shown in figure 3, the arc extinguishing type protective device of the present embodiment can also include indication mechanism 116, wherein indication mechanism
116 connect with control 102 signal of chip.During specific implementation at one, if monitoring personnel is at the scene, can no longer it pass through
Terminal checks related data, but directly can get related data from arc extinguishing type protective device by indication mechanism 116.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention belong to the scope of protection of present invention.
