Abstract

The invention discloses a server system power supply line. The server system power supply line comprises an input end, a protective circuit, an output end, a transient voltage suppressor and a first resistor, wherein the input end is used for being connected with a power source and receiving electricity input by the power source, the protective circuit is connected between the input end and the output end and used for monitoring input electricity in the power supply line and controlling and regulating the input electricity of the power supply line so as to maintain input electricity parameter values within the preset range, the output end is used for being connected with a server system, the transient voltage suppressor is connected to the input end of the protective circuit, a negative electrode of the transient voltage suppressor is connected with the input end of the protective circuit, the positive electrode of the transient voltage suppressor is grounded, and the first resistor is connected with the transient voltage suppressor in series and fused when current is higher than a threshold value. According to the server system power supply line, if the transient voltage suppressor is broken down by excessively-high transient pulse voltage produced in the circuit to be short-circuited, the first resistor connected with the transient voltage suppressor in series is fused, the transient voltage suppressor can be disconnected from the power supply line, and therefore the phenomenon that a server system is powered down due to the fact that the transient voltage suppressor is short-circuited is avoided.

Description

technical field [0001] The invention relates to the technical field of server system power supply, in particular to a server system power supply circuit. Background technique [0002] Server systems have very high requirements on stability, and the stability of power supply is the basis for ensuring system stability. [0003] In the prior art, a protection circuit is added to the power supply line to realize the overvoltage protection and overcurrent protection of the server system power supply. For example, a hot-swap (Hot-Swap) circuit is added to the line as a soft start. Refer to figure 1 , is a schematic diagram of a power supply line used in the prior art. In this type of power supply line, during overvoltage protection or overcurrent protection, there may be instantaneous voltage spikes, which are mostly generated when the circuit triggers protection or cuts off Q1, and the instantaneous pulse voltage generated by this will cause heat Plugging and unplugging the con...
