Title: Protecting device for voltage-dividing type chopper
Inventor: TACHIBANA MEGUMI
IPC: H02M3/00
Filed: 1982-03-31
Abstract: PURPOSE:To enhance the reliability of a protecting device for a voltage-dividing type chopper without using a special circuit by detecting the differential voltage between terminals of a voltage dividing condenser and indicating a trouble of a chopper. CONSTITUTION:Voltages of voltage-dividing condensers are respectively detected by detectors 31, 32, and the output unbalance of the detectors 31, 32 is calculated by an arithmetic circuit 33. When the output of the arithmetic circuit 33 exceeds the set value 34, the switch is operated by the output 38 of a comparison arithmetic circuit 36 to open a main circuit. The set value is set to a value which is larger than the set value 34, i.e., to a value which is considered to be due to damage of an element, and when the voltage difference of the shared voltages of the two voltage dividing condensers exceeds the set value, the value is stored in a memory circuit 39 together with the polarity of the voltage difference, and even after the main circuit is opened, indication lamps 40, 41 are energized.

Abstract: PURPOSE: To miniaturize the control valve by sliding a spool provided with variable orifice by a pilot hydraulic pressure in the direction which is perpendicular to the direction of the hydraulic operating fluid for said valve of hydraulic pressure elevator and the like, and controlling the amount of the hydraulic operating fluid.  
     CONSTITUTION: The hydraulic operating fluid which is applied on the upper surface of a valve case 41 flows to the lower surface side of the valve case 41 via an inlet port 44, a valve chamber 42, outlet ports 45a and 45b, and a through hole 51. At this time the amount of hydraulic operating fluid flowing in the valve chamber 42 is controlled by sliding the spool 43 by the pilot hydraulic pressure which is applied from an oil introducing port 50, and by varying the opening area of a variable orifice 47 provided in said spool 43. Since the spool 43 is slidden in the direction which is perpendicular to the hydraulic operating fluid flowing direction and the opening area of the variable orifice 47 is varied, the spool 43 can be made compact, and its diameter also can be made short. Therefore, the control valve also can be made compact.
