Capacitor box and capacitor box device

The embodiment of the utility model provides a capacitor box and a capacitor box device. The capacitor box is used for being connected to a direct current bus of a driver and comprises a first number of branch circuits; each branch circuit comprises a second number of resistor-capacitor pairs formed by connecting a resistor and a capacitor in parallel; wherein for each resistor-capacitor pair, the current flowing through the resistor in the resistor-capacitor pair is greater than the leakage current of the capacitor in the resistor-capacitor pair. Capacitance boxes can be formed in a modularized mode and spliced, and flexibility and practicability are improved. 本实用新型实施例提供了一种电容箱及电容箱装置。该电容箱用于连接到驱动器的直流母线，包括：第一数量的分支电路；每一个分支电路中包括第二数量的由一个电阻以及一个电容并联在一起形成的电阻电容对；其中，对于每一个电阻电容对，流过该电阻电容对中电阻的电流大于该电阻电容对中电容的漏电流。能够以模块化的方式组成电容箱并进行电容箱的拼接，提高了灵活性及实用性。
