Abstract

The invention provides a surge protection device comprising a Y-shaped pressure-sensitive chip, and a distribution box. The surge protection device comprising the Y-shaped pressure-sensitive chip comprises an insulated fixing seat, the Y-shaped pressure-sensitive chip, a first electrode and a second electrode, wherein the first electrode and the second electrode are used for being connected with an external circuit, the Y-shaped pressure-sensitive chip is fixed on the fixing seat, the Y-shaped pressure-sensitive chip comprises an electrode A, an electrode B, an electrode C, a first piezoresistor chip and a second piezoresistor chip, the first piezoresistor chip is located between the electrode A and the electrode B, the second piezoresistor chip is located between the electrode A and the electrode C, the electrode B is electrically connected with the second electrode, and the electrode C is electrically connected with the first electrode. The surge protection device comprising the Y-shaped pressure-sensitive chip, and the distribution box can be used in a direct current system and an unconventional 690 VAC and above power system, and the safety performance is higher.

Description

technical field [0001] The invention relates to the field of circuit protection devices, in particular to a surge protector and a distribution box including a Y-shaped pressure-sensitive chip. Background technique [0002] The surge protector formed by the Y-shaped varistor chip contains a Y-shaped varistor chip, such as figure 1 As shown, the chip is composed of electrodes (A, B, C) and zinc oxide varistor chips (M1, M2). In a conventional 380V system, electrode A-chip M1-electrode B constitutes a lightning leakage channel, and the electrode A-chip M2-electrode C forms a lightning leakage channel. At present, the pressure-sensitive chip is only used in some low-capacity surge protectors. In high-capacity surge protectors, it is not used due to the difficulty of its tripping mechanism. At the same time, it is used in DC systems and unconventional The surge protector formed by the Y-type varistor chip of this connection method cannot be used in the power system of 690VAC an...
