Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0025] In the embodiment of the present invention, an automatic load limiting protector includes a housing on which an input end 101 and an output end 102 are provided, the input end 101 is connected to the main gate, the output end 102 is connected to the load, and the protector shell The body is provided with a first circuit breaker 1 and a second circuit breaker 2, the incoming line ends of the first circuit breaker 1 and the second circuit breaker 2 are connected to the input end 101, and the outgoing line ends are connected to the output end 102, wherein, The second circuit breaker has a reclosing function. The automatic load limiting protector collects the current signal of the first circuit breaker 1 through the transformer input circuit and sends it to the control chip of the CPU logic circuit through the load signal anti-interference input circuit. T...

Abstract

The invention relates to an automatic load limiting protector. According to the automatic load limiting protector, a shell is provided with a first circuit breaker and a second circuit breaker; the automatic load limiting protector collects a load signal of the first circuit breaker through a mutual inductor and sends the load signal to a control chip; when the load connected with the first circuit breaker exceeds a current set value, the control chip controls the second circuit breaker to cut off the power supply; when the load of the first circuit breaker returns to normal, the power supplyof the second circuit breaker returns to power on. The automatic load limiting protector can achieve the control among loads; when the electric load of a first load exceeds a set value, the power supply of a second load is automatically cut off, thereby ensuring that the load of the first circuit breaker continues to work and the total brake does not overload trip; when the second load is recovered, the second load is recovered at the same time; the load stability of the electric network is ensured by temporarily limiting the urgent need of the electric equipment to the urgent need of the non-urgent need of the electric equipment; the three-phase load balance of the power grid is kept; electrical equipment can be used to avoid peak operation, thereby ensuring the normal operation of the power grid.

Description

technical field [0001] The invention relates to a load protector, in particular to an automatic load-limiting protector. Background technique [0002] The load limiting protector is used for automatic control of electricity consumption in hotels, student dormitories, factory dormitories, civil houses on construction sites, and places where the specified power is used. Mainly to restrict the illegal use of resistive load power electric heating equipment. However, the existing load-limiting protector is generally connected to one electrical device, and can only perform load monitoring and switch control on one load, and has a single function. In some places, such as households, there are many electrical equipment and the power environment is more complicated, and the power of different electrical equipment is different. When multiple electrical equipment is connected to the grid at the same time, when there is a high-power At this time, if all the electrical equipment is in ...
