专利汇可以提供Electric load control专利检索，专利查询，专利分析的服务。并且A secondary electric load is connected to a source of electric potential through a thyristor the activation of which is controlled automatically by a current transformer which senses the electric current in the main supply circuit or in the supply circuit of a primary load, the thyristor being deactivated when the sensed current reaches a predetermined magnitude.，下面是Electric load control专利的具体信息内容。

权利要求

1. A control for an electric load circuit connected to an electric supply circuit, comprising: a. thyristor means in said load circuit arranged in series with the load, b. the thyristor means including a gate control element having an electric gate voltage supply circuit, c. switch means in said gate voltage supply circuit for selectively supplying and removing gate voltage for said thyristor means, d. electric switch operator means having an electric circuit, and e. a current transformer in the electric switch operator means and arranged to operatively couple the circuit of the switch operator means to said electric supply circuit in parallel with the circuit of the load for sensing the electric current in said supply circuit, f. the electric switch operator means being activated upon attainment of a predetermined magnitude of sensed current in the supply circuit to operate the switch means to open the electric load circuit.

2. The control of claim 1 wherein thE current transformer is a toroidal current transformer.

3. The control of claim 1 wherein the switch means is the contact of a relay and the switch operator means is the coil of said relay.

4. The control of claim 3 including variable resistance means across said coil for effecting activation of the relay at various selected load levels sensed by the current transformer.

5. The control of claim 1 wherein the current transformer is arranged to be coupled directly to said electric supply circuit.

6. The control of claim 1 wherein a second electric load circuit is connected to the electric supply circuit in parallel with the load circuit to be controlled, and wherein the current transformer is arranged to be coupled to said second electric load circuit.
